Answer:

15in

Step-by-step explanation:

Convert the 15 ft to inches (180) and then set up the proportion.\frac{1}{12} = \frac{x}{180}121=180x .  Cross multiply to get that 12x = 180 and x = 15 inches.

Answer:

$52.5

Step-by-step explanation:

Whenever there is a sales tax of a certain percentage, you need to first convert that percentage to decimal. 5%=0.05, and multiplying this by the overall price gives 0.05*50=$2.5. Adding this to the initial price of $50, you get 50+2.5=$52.5. Hope this helps!
