Nancy and her sister went to the store together. After the store, Nancy walked 2 blocks west to get a coffee and her sister walked 7 blocks west back to work. How many blocks is the coffee shop that Nancy went to from her sister's work?

5x+2x=49

7x=49

x=7. 35 apples

47 - 90 = 43

43 - 180 = x

x = 137

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
