Answer:
substitution method
x = 7
y = 2
Step-by-step explanation:
2x - 2y = 10
x = 7
substitute for x:
2(7) - 2y = 10
14 - 2y = 10
subtract 14 from each side of the equation:
-2y = -4
divide both sides by -2:
y = 2

The question is find the total cost when the price is $89.75 and the tax is 7 1/4%
Total cost = price + tax
Tax = 7 1/4 % of price
Tax rate = [7 + 1/4] = 7.25 %
Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51
Total cost = $89.75 + $ 6.51 = $96.26
