Alyssa has total of 5 quarters and dimes. the total value of the coins is $1.95. how many of each coins does she have?

7 Dimes

Step-by-step explanation: If Alyssa has 5 quarters then she also has 7 dimes if she has a total of $1.95.

5 x .25 = 1.25

Then calculate the difference between the quarters and the total - $1.95-1.25=.70

Then divide the difference by the value of a dime (.10) - .70/.10= 7

Therefore, she has 7 dimes.

tangent

step-by-step explanation:

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).
