Trent already had 28 flowers in his garden and he can also grow 1 flower with every seed packet he uses. How many seed packets does Trent need to have a total of 43 flowers in his garden

15 seed packets

Step-by-step explanation:

First we need to find how many more flowers he needs to grow.

This can be modeled by the expression:

43-28=15.

We know that every flower needs one seed packet, so we can multiply that number by the number of flowers he still needs to grow:

15*1=15

This means he still needs 15 seed packets.
