Question

1) Andrea rents a bike for a day. The rental charges can be determined by

Answer 1

Answer:

$0.5

Step-by-step explanation:

We have been given an equation $R=\ 0.5d$, where R is rental charges and d is number of days  Andrea rents the bike. We are asked to find the unit rate.

We know that unit rate represents the ratio between two different quantities. Unit rate represents how many units of one quantity are equal to one unit of another quantity.

Let us divide both sides of given equation by d:

$\frac{R}{d}=\frac{\ 0.5d}{r}\\\\\frac{R}{d}=\ 0.5$

Therefore, the unit rate for our given problem would be $0.5, which represents rental charges per day.
