Marta received $5 for her dad in the back yard. (a) write an inequality to show how much money marta can spend when she goes to the store. answer this with a valid response, if your not sure don't put in a answerif you answer correctly you may or may not receive brainiest .

 x ≤ $5

Step-by-step explanation:

Marta can spend NO MORE than $5.

"No more" is the same as saying LESS THAN OR EQUAL TO.

The symbol for "less than or equal to" is:   ≤

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).
