Answer:
10x + 7 = 85
8 packs
Step-by-step explanation:
Let's let packs = x
10 shirts in a pack = 10x
So we know that since he has 7 packs already, that can be our y-intercept in this equation
This will leave us with 10x + 7
And since we can't have a partial amount of packs, we round up to 8 total packs
Hope this helps
