Let's go over the word problems shown in the image.

Problem 14:

Linsey bought a bag of dog food for $12.50 and a food bowl for $6.33. To find out how much she spent, we simply add these two amounts together:

$12.50 + 6.33 = 18.83$

So, Linsey spent $18.83.

The correct answer is $18.83.

Problem 15:

A truck had 6.3 tons of dirt, and it dumped 4.9 tons. To find out how much dirt is left, we subtract the amount dumped from the initial amount:

$6.3 - 4.9 = 1.4$

The truck has 1.4 tons of dirt left.
