24. the junior class is selling spirit-wear in
order to raise $1800 for the prom.
sweatshirts cost $25 and t-shirts cost $15.
the equation that models this situation is
25x+15y = 1800, graph the equation by finding
the intercepts. identify three solutions to
them plan the fundraiser

5/20 so 25%

step-by-step explanation:

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

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).

it is 32.5

i hope i could u.
