Question

It costs $5.15 to buy 1/4 oz of walnuts. how much would it cost to purchase 4.5 oz of walnuts.

Answer 1

If it costs $5.15 to buy 0.25 oz of walnuts, then we can use the next proportion to find how much would it cost to purchase 4.5 oz of walnuts.:

`\frac{5.15\text{ \$}}{x\text{ \$}}=\frac{0.25\text{ oz}}{4.5\text{ oz}}`

Solving for x,

`\begin{gathered} 5.15\cdot4.5=0.25\cdot x \\ 23.175=0.25\cdot x \\ (23.175)/(0.25)=x \\ 92.7=x \end{gathered}`

It would cost $ 92.7 to purchase 4.5 oz of walnuts.​
