Jerry set a goal to run 16 miles during the school week. He ran 3.42 miles on Monday and 2.7 miles on Tuesday. How many miles does Jerry have left to run this week to meet his goal?

To find out how many miles Jerry has left to run this week to meet his goal of 16 miles, we first need to calculate how many miles he has already run.

On Monday, he ran 3.42 miles, and on Tuesday, he ran 2.7 miles.

Adding these two distances together:

\[ 3.42 + 2.7 = 6.12 \text{ miles} \]

Now, we subtract the total miles he has run from his goal:

\[ 16 \text{ miles} - 6.12 \text{ miles} = 9.88 \text{ miles} \]

So, Jerry has 9.88 miles left to run this week to meet his goal.
