Studdy Solution

STEP 1

Assumptions1. Rob will be81 years old in ten years.

STEP 2

We need to find Rob's current age. We can do this by subtracting the number of years in the future (10 years) from his future age (81 years).
$Current\, age = Future\, age - Number\, of\, years\, in\, the\, future$

STEP 3

Now, plug in the given values for the future age and the number of years in the future to calculate Rob's current age.
$Current\, age =81\, years -10\, years$

STEP 4

Calculate Rob's current age.
$Current\, age =81\, years -10\, years =71\, years$ Rob is71 years old.
