Answer: True
Interest is a fee paid for the use of money over time.
Distribute the outside number (the 2 fractions in this case) to the numbers in the parenthesis. Multiply them and then solve for the variable. To solve for variable just add or subtract the constant (add if negative subtract if positive). Then divide each side with the number paired with the variable.

Your formula is right but you must have plugged it in wrong.
Y= 1/10 x
X is your distance, so plug in 85 with x
Y= 1/10 85
One- tenth as a decimal equals 0.1. So 0.1 times 85 will equal 8.5
