Vaughn paints his porch floor and also the porch floors of 9 neighbors. Each floor is a rectangle that is 8.2 feet long and 6.7 feet wide. What is the exact total area of all the porch floors that Vaughn paints? Enter your answer in the box. (My little sister needs help but I can't help her right now)

494.46 feet²

Step-by-step explanation:

So the area of one porch floor is

=l×w

=8.2×6.7 feet²

=54.94 feet²

So he paints 9 porch floors

So the exact total area of all the porch floors that Vaughn paints is

=54.94×9 feet²

=494.46 feet²

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
