Select an Answer Question 4 $2500 was invested at 6% and The Math Club raised $5000 to attend a future competition. The club invested part of the money in an account that paid 6% interest, and the rest in a government savings bond that paid 8% interest per year. After one year, the club had earned a total of $330 in interest. The linear system that models this situation $2500 was invested at 8%. is z +y = 5000 0.06z + 0.08y = 330 $3500 was invested at 89% and $1500 was invested at 89%. where z is the amount invested at 6% and y is the amount invested at 8%. How much was invested at each rate? $3500 was invested at 6% and E Calc $1500 was invested at 89%. $2500 was invested at 8% and $2500 was invested at 6%.

Biology Each day, an average adult moose can process about 32 kilograms of terrestrial vegetation (twigs and leaves) and aquatic vegetation. From this food, it needs to obtain about 1.9 grams of sodium and 11,000 calories of energy. Aquatic vegetation has about 0.15 gram of sodium per kilogram and about 193 calories of energy per kilogram, whereas terrestrial vegetation has minimal sodium and about four times as much energy as aquatic vegetation. Write and graph a system of inequalities that describes the amounts t and a of terrestrial and aquatic vegetation, respectively, for the daily diet of an average adult moose.
