Vlad spent 20 minutes on his homework and then completely solved x math problems that took 2 minutes to complete. What is the equation tat can be used to find the value of y, the total that Vlad spent on his homework, and what are the constraints on the values on the values of x and y

20 divided by 2 = 10

Step-by-step explanation:

the weight of the object inside the box!

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).
