Question

judy is selling 8 ribbons for 10 dollars sarah wants to buy 5 if judy pays the same rate how much sould she pay fo 5 ribbons

Answer 1

JUdy will pay $6.25

Step-by-step explanation

Step 1

find the rate

`\frac{8\text{ ribbons}}{10\text{ dolars}}=0.8\frac{\text{ribbons}}{\text{dollar}}`

Step 2

if Judy pays the same rate how much should she pay for 5 ribbons

let

y represents the amount Judy pays at the same rate by the 5 ribbons

`\begin{gathered} 0.8\frac{ribbons\text{ }}{\text{dollar}}=\frac{5\text{ ribbons}}{y} \\ 0.8=(5)/(y) \end{gathered}`

Step 3

finally, solve for y

`\begin{gathered} 0.8=(5)/(y) \\ 0.8y=5 \\ y=(5)/(0.8) \\ y=6.25 \end{gathered}`

Hence, Judy will pay $6.25
