Answer:
If 2p + 6a = $14
and 3p + 9a = $21
then the following would also be true:
1p + 3a = $7
If p = pear and a = apple, how much would each cost? The unit prices can be determined by looking at the pattern. You can use multiplication to solve the problem.
For example, 1p + 3a*2 = $7
p = $1/each
a = $2/each or $6 total
