Your beginning balance on your lunch account is $55. You buy lunch for 1.75 everyday and sometimes buy a snack for $0.85 after 2
Agata [3.3K]
Multiply 1.75 with 25 because you bought snacks everyday and then you’re left with 11.25

Now subtract .20 because you were left with that on day 26 and you get 11.05

Lastly you divide 11.05 with .85 to see how many snacks you bought

ANSWER IS 13 snacks
