Answer:
2.39 per bottle
Step-by-step explanation:
x = cost of one juice bottle
15 should be multiplied by x to find how much 15 juice bottles cost
1.95 should be added as a constant since it should be accounted for.
37.80 should be made equal to the above to make this:
15x + 1.95 = 37.80 and solve for x
15x = 35.85
x = 2.39
Hope this helps!
