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.
Equivalent fractions are two or more fractions that have the same value, despite having different numerators/denominators.
This reduced fraction would be c. x+y/8.
You can apply the Difference of Two Squares Formula (x^2+y^2)=(x+y)(x-y). Then, you can factor out the common term 8 and cancel out the common factor x-y. Hope this helps! :)
Idk if you want a specific number but here's an example.
Some ways you can write a number are as a decimal, as a percentage, and as a decimal.
5 as a fraction is
5 as a percent is 5%
5 as a decimal is .20
