Question

Must use a diagram to show math work : tape diagram, ratio table or double number line diagram

Answer 1

a) The most number of potato "x" she can spend $5 on will be 10potatoes

b) The cost of 15 potatoes is $7.5

Step-by-step explanation:

1) From the question, the corner market sells potatoes at a rate of 1/2 dollars per potato.

`\$(1)/(2)=1\text{ potato}`

If Amanda is able to spend $5 on potatoes, the most number of potato "x" she can spend will be:

`\$5=x`

Divide both expressions to get the most number of potatoes "x"

`\begin{gathered} ((1)/(2))/(5)=(1)/(x) \\ (0.5)/(5)=(1)/(x) \\ 0.5x=5*1 \\ 0.5x=5 \\ x=(5)/(0.5) \\ x=10\text{potatoes} \end{gathered}`

Hence the most number of potato "x" she can spend $5 on will be 10potatoes

Using the tape diagram;

2) Since 1 potato cost $0.5, the cost of 15 potatoes will be expressed as:

Cost of 15 potatoes = 0.5 * 15

Cost of 15 potatoes = $7.5

Hence the cost of 15 potatoes is $7.5
