Monica found the volume of the prism below using the expression 4 + (4 times one-half).What errors did Monica make? Check all that apply. She should have counted only 2 unit cubes instead of 4. She should have counted 8 one-third cubes instead of only 4. She should have found the total value of the one-third cubes by multiplying by One-third instead of by One-half. Each fractional cube is worth Two-thirds instead of the One-half that she used. She cannot stack more than one layer of fractional cubes in a prism.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

if you need just tell me and i will come to the rescue.

step-by-step explanation:

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
