Melissa finished her chemistry assignment in 1/4 hours. Then she completed her history assignment in 2/5 hours. What was the total amount of time Melissa spent doing these two assignments?

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

5 + 8 +7 + 4 + 0 +1 = 25
