- For the following exercises, write a system of equations that represents the situation. Then, solve the system using the inverse of a matrix. 58. Anna, Ashley, and Andrea weigh a combined 370 lb. If Andrea weighs 20 1b more than Ashley, and Anna weighs 1.5 times as much as Ashley, how much does each girl weigh?arrow_forwardFor the following exercises, write a system of equations that represents the situation. Then, solve the system using the inverse of a matrix. 54. A food drive collected two different types of canned goods, green beans and kidney beans. The total number of collected cans was 350 and the total weight of all donated food was 348 1b, 12 oz. If the green bean cans weigh 2 oz less than the kidney bean cans, how many of each can was donated?arrow_forwardFor the following exercises, write a system of equations that represents the situation. Then, solve the system using the inverse of a matrix. 55. Students were asked to bring their favorite fruit to class. 95% of the fruits consisted of banana, apple, and oranges. If oranges were twice as popular as bananas, and apples were 5% less popular than bananas, what are the percentages of each individual fruit?arrow_forward
- Solve the system by using substitution: {4x2+y2=4y=x+2.arrow_forwardFor the following exercises, write a system of equations that represents the situation. Then, solve the system using the inverse of a matrix. 60. A farmer constructed a chicken coop out of chicken wire, wood, and plywood. The chicken wire cost $2 per square foot, the wood $10 per square foot, and the plywood $5 per square foot. The farmer spent a total of $51, and the total amount of materials used was 14 ft2. He used 3 ft2 more chicken wire than plywood. How much of each material in did the farmer use?arrow_forwardSolve the system by substitution: {2x+y=14x+3y=3 .arrow_forward
- For the following exercises, write a system of equations that represents the situation. Then, solve the system using the inverse of a matrix. 52. 2,400 tickets were sold for a basketball game. If the prices for floor 1 and floor 2 were different, and the total amount of money brought in is $64,000, how much was the price of each ticket?arrow_forwardTranslate to a system of equations and then solve: Erin spent 30 minutes on the rowing machine and 20 minutes lifting weights at the gym and burned 430 calories. During her next visit to the gym she spent 50 minutes on the rowing machine and 10 minutes lifting weights and burned 600 calories. How many calories did she burn for each minutes on the rowing machine? How many calories did she burn for each minute of weight lifting?arrow_forwardTranslate to a system of equations and then solve: Jason paddled his canoe 24 miles upstream for 4 hours. It took him 3 hours to paddle back. Find the speed of the canoe in still water and the speed of the river current.arrow_forward
- Use the system of three equations in three variables to solve each problem. Work schedules A college student earns 198.50 per week working three part-time jobs. Half of his 30-hour work week is spent cooking hamburgers at a fast-food chain, earning 5.70 per hour. In addition, the student earns 6.30 per hour doing janitorial work. How many hours per week does the student work at each jobarrow_forwardTranslate to a system of equations and solve: Leon had $50,000 to invest and hopes to earn 6.2% interest per year. He will put some of the money into a stock fund that earns 7% per year and the rest in to a savings account that earns 2% per year. How much money should he put into each fund?arrow_forwardFor the following exercises, write a system of equations that represents the situation. Then, solve the system using the inverse of a matrix. 53. In the previous exercise, if you were told there were 400 more tickets sold for floor 2 than floor l, how much was the price of each ticket?arrow_forward
