Answer 1

Finding the amount of money that Juan needs to purchase the supplies:

Given,

Juan has $\$10$ and the cost of purchasing supplies is $\$13$

We need to subtract the amount Juan needs to purchase supplies by how much he has in order to find the amount he is short of.

Therefore, Juan is short of,

$$\begin{gathered} =\$13-\$10 \\ =\$3 \end{gathered}$$

Therefore, Juan is short of $\$3$ to purchase the supplies.
