Answer:
2
Step-by-step explanation:
I think below is your full question:
<em>Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories.
</em>
<em>If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?</em>
Here is my answer
Let x is number of shirts
Person COST
ERIN 12x+18
DAN 16x+10
Equally Billed 12x+18=16x+10 <=> x = 2
so each of them buy 2 shirts
307.85
-40
-9.50
-41.75
+23.75
-4.62
=235.73$
3.75 divided by 3= 1.25
3.75-1.25= 2.50
