Question

an ice cream with 3 packets of chips cost 3.60 dollars while 3 ice creams and 2 packets of chips cost 5.20 dollars calculate the cost of one ice cream the cost of one ice cream is______

Answer 1

Answer:

1.20

Step-by-step explanation:

Let the packet of an ice - cream be of Rs. x

Let the cost of one packet chips be Rs. y

According to question,

x + 3y = 3.60

x = 3.60 - 3y ________ (1)

3x + 2y = 5.20 ________(2)

Substitute eq. (1) in eq. (2), we get

3 ( 3.60 - 3y ) + 2y = 5.20

10.8 - 9y + 2y = 5.20

10.8 - 5.20 = 7y

5.6 = 7y

y = 0.8

We know that,

x = 3.60 - 3(0.8)

= 3.60 - 2.40

= 1.20
