Frank builds a miniature model of a car based
on the dimensions of a popular car. He uses a
scale of 1 foot = 0.2 inch. Determine the length
of the miniature model, if the actual car is 13.5
feet long.

2.7 inches long

Step-by-step explanation:

cross multiply

1 * x = 13.5 * 0.2

x = 2.7

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
