Answer: r+7
Whatever his age is now, we add 7 to it. So we simply add 7 to r getting r+7.

r = 10
r+7 = 10+7 = 17
meaning he will be 17 seven years from now

Step 1:
Find the difference between the two numbers.
$2.40-$1.44= $0.96
Step 2:
Divide by the original number.
$0.96/1.44= 0.667
Step 3:
Multiply by 100 to find percent increase.
0.667 * 100= 66.7% rounded to one decimal place or 67% rounded
