a student usually saves $45 a month. He would like to reach a goal of saving $700 in 12 months. The student writes the equation 700= 12(x+45) to represent the situation. Solve the equation for x.

in this case, x is the amount more he needs to save per month

350=12(x+20)

distribute

350=12x+240

minus 240 both sides

110=12x

divide both sides by 12

9.166666=x

needs to save about $9.17 more per  month or 29.17 permonth

Step-by-step explanation:

sorry if its wrong i tried and maybe i could get brainliest?

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).
