At a fundraiser breakfast, the bill for three glasses of orange juice and five pancake specials is $7.60, whereas the bill for one glass of orange juice and two pancake specials is $2.90. . . a.Write a system of two equations to model this problem. Let j stand for the price of a glass of juice and let p stand for the price of a pancake special.. . b.Use the substitution method to solve the system of equations.. . c.What would be the bill for one glass of orange juice and one pancake special?.

Respuesta :

A ) 
3 j + 5 p = 7.60
j + 2 p = 2.90
B ) 
j = 2.90 - 2 p
3 ( 2.90 - 2 p ) + 5 p = 7.60
8.70 - 6 p + 5 p = 7.60
p = $1.10
j = 2.90 - 2.20
j = $0.70
C ) 
The bill for 1 glass of orange juice and 1 pancake special would be:
0.70 + 1.10 = $1.80
