STEP 1
We convert the 5 years to months.
Since there are 12 months in 1 year, therefore in 5 years we would have:
12 x 5 years= 60 months
STEP 2
Since the athlete would earn $1.3 x 10^6 per month
In 5 years she would earn
STEP 3
we would convert the solution to scientific notation, therefore the answer is
In conclusion, the answer is $ 7.8 x 10^7
