A company is upgrading office technology by purchasing inkjet printers, LCD monitors, and additional memory chips. The total number of pieces of hardware purchased is 49. The cost of each inkjet printer is $104, the cost of each LCD monitor is $140, and the cost of each memory chip is $91. The total amount of money spent on new hardware came to $5226. They purchased two times as many memory chips as they did LCD monitors. Determine the number of each that was purchased. Write a linear system of equations. Let x be the number of inkjet printers, y be the number of LCD monitors, and z be the number of memory chips. Choose the correct answer below. 104x+140y+91z=5226 x+y+z=49 -2y+z=0 The company purchased ____ inkject printers. LCD monitors, and ____memory chips.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
