Answer:
10.4 miles
Step-by-step explanation:
Write an equation for the total cost paid as a function of the # of miles driven:
L(x) = $6.75 + ($3.20/mile)x
and set this equal to $40.03 to determine the # of miles Lupita rode:
L(x) = $6.75 + ($3.20/mile)x = $40.03
Isolate the x term by subtracting $6.75 from both sides:
($3.20/mile)x = $40.03 - $6.75 = $33.28
Finally, divide both sides by ($3.20/mile):
x = $33.28 / ($3.20/mile)
= 10.4 miles
Lupita rode 10.4 miles in the taxi.

Answer:
30.67 feet
Step-by-step explanation:
A proportion is often useful for solving scale drawing problems.
actual size : drawing size = (room length) : (23 in) = (2 ft) : (1.5 in)
Multiplying by 23 in gives ...
room length = (2 ft)(23 in)/(1.5 in) = 46/1.5 ft = 30 2/3 ft
room length ≈ 30.67 ft.
