Answer:
We conclude that Jonathon already jogged this summer 18 miles.
Explanation:
We know that Jonathon has a goal to jog at least 150 miles this summer. Jonathan jogs and an average of 3.3 miles per day. Jonathan must jog each day for the rest of the summer to achieve his goal and there are 40 days left in summer.
Therefore, we have equation:
M+40 times 3.3=150
M+132=150
M=150-132
M=18
We conclude that Jonathon already jogged this summer 18 miles.
