We want to slove the given equations using reverse order of operation

1. x - 4 = -2

Reverse subtraction of 4

x - 4 + 4 = -2 + 4

x = 2

2. a + 10 = -4

Reverse addition of 10

a + 10 - 10 = -4 - 10

a = -14

3. 59 = s + 90

Reverse addition of 90

59 - 90 = s + 90 - 90

-31 = s

s = -31

At Bed Bath and Beyond, the manager, Jill Roe, knows her customers will pay no more than $300 for a bedspread, Jill wants a 35%
lora16 [44]

Answer:

195

Step-by-step explanation:

I would tackle this question with cross multiplying.

 x          65

---    =   ------

300        100

The 300 is the price the customer will pay and x is the amount Jill bought it for. Because Jill wants a 35% markup, that means she is willing to pay 65% what her customers will pay (100-35=65). so we put the 65 over 100 on the other side of the equals sign and cross multiply it out.

100x=19500

Divide both sides by 100 and you get

x=$195

So your answer is: The most Jill Roe can pay for a bedspread is $195.
