Answer:
Total price = $112.70
Step-by-step explanation:
Total price of all three items without tax = 4 + 94 + 6.35
= $104.35
Total price of all three items with tax = (100% + tax) * Price
= (100% + 8%) * 104.35 = 108% * 104.35
= 1.08 * 104.35 = 112.698
≅ $112.70
(2) Explain how to use estimation to check whether your answer is reasonable:
We can use estimation to check if a result is reasonable by plugging in the answer in the original equation.
E.g. x + 4 = 10; x = 10 - 4
We get that x = 6
Plug in x = 6 in x + 4 = 10.
6 + 4 = 10. Indeed the answer was a reasonable one.
46 - 4 = 3b + 3
Simplify the left side:
42 = 3b + 3
Subtract 3 from both sides:
39 = 3b
Divide both sides by 3:
b = 13
Answer: $34
Step-by-step explanation:
39 x 0.2 = 7.80, the discount
39 - 7.80 = 31.20
31.20 x 0.09 = 2.80, the tax
31.20 + 2.80 = 34
Total cost for the shoes: $34
