Answer:

3 people

Step-by-step explanation:

Let "x" represent the number of people who payed with cash

Let "y" represent the number of people who payed with credit card

14x +15y = 177 ---------1

3x =y--------- 2

solving simultaneously,

put eqn 2 into eqn 1

14x + 15 (3x) = 177

14x + 45x = 177

59x = 177

x=3

From eqn 2 , y = 3 x

y = 3 (3)

y=9

therefore the number of people who paid with cash were 3.
