Peter is going to put up 5 walls in the tree house. Each wall will be 7 feet high and 7 feet across. He wants to leave room for windows that measure 2 feet by 2 feet. Which algebraic expressions will give the total square feet of lumber he will need for the walls if n represents the number of windows he puts in? Choose all that apply. 241n 49n – 4 49n – 4n 245 – 4n 49(5) – 4n (7)(7)(5) – 4n (7)(7)(5) – (2)(2)n

245 – 4n,    49(5) – 4n,    (7)(7)(5) – 4n,    (7)(7)(5) – (2)(2)n,

it would more likely be bald eagle because its has more in the box so about 75%.

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
