Been stuck on this please help fast

63

Step-by-step explanation:

we can first find the area of the individual shapes. first, the rectangle's area

A=l*w

A=5*9

A=45

we are given the height of the triangle (9) so we can find the total area of the triangles

Total Area of Trangles = (bh/2)*2

=bh

=2*9

=18

now add the two areas together

18+45

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
