Answer:
Each roll is approximately worth $1.7
Step-by-step explanation:
In order to find the unit rate, divide the quantity by the price.
In this case, divide 5 by 3.
5/3= 1.6666666667 (~1.7)
The ratios are set equal to each other which is constant. Then the cost of one roll is $0.6.
A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given
Stop & Shop is having a sale on paper towels: 5 rolls for $3.
Let the cost of one roll be x dollar. Then we know that the ratio remains constant.
[tex]\rm \dfrac{x}{1} = \dfrac{3}{5}\\\\x \ = 0.6[/tex]
Thus, the cost of one roll is $0.6.
