Question

A man bought four cups of coffee and left a $7 tip. A woman bought eight cups of
coffee and only left a $2 tip. If they paid the same amount, how much was each cup
of coffee?
a. $1.10
b. $2.25
c. $0.75
D.1.25

Answer 1

8c + 2 = 4c + 7

8c - 4c = 7 - 2

4c = 5

c = 5/4

c = $1.25

Each cup of coffee was $1.25
