Answer 1

Oranges cost $4.55 for 7 lb. At that rate, how many pounds of oranges can you buy for $7.15?​

step 1

Find the unit rate

divide the total cost by the total pounds

so

4.55/7=$0.65 per lb

step 2

Applying proportion

$0.85/1 lb=$7.15/x

solve for x

x=7.15/0.65

x=11 lb

therefore

the answer is 11 pounds
