Question

Please help

ok it's blurry sorry

Answer 1

The equation is:
12.99 + 2.10b = 21.39
Subtract 12.99 from each side to get:
2.10b = 8.4
Then divide to find the amount of bottles:
b = 4 bottles

Hope this helps!! :)

Answer 2

21.39 - 2.10b - 12.99 = 8.4 - 2.10b
8.4 - 2.10b = 0
8.4 = 2.10b
8.4/2.1 = 2.10b/2.1

b = 4

hope this helps
