Question

If 2 pounds of strawberries cost $4.50 how much would 3 pounds cost?

Answer 1

we know that

`2` pounds of strawberries cost
`\$4.50`

so

by proportion

Find the cost of
`3` pounds of strawberries

`(4.50)/(2) (\$)/(pounds) =(x)/(3) (\$)/(pounds)\\ \\x=(4.50*3)/2\\ \\x=\$6.75`

therefore

the answer is

`\$6.75`
