Question

I'm a little stumped, can anyone help? I will FAN and MEDAL the person who answers this the best.

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?

Answer 1

Part A you get:
7.6=3j+5p
2.9=1j+2p

Answer 2

For B ~
isolate j from the second equation,
then substitute it in the first equation

Answer 3

7.6=3(2.9−2p)+5p

Answer 4

solve for p can you?

Answer 5

@Zoe9639 can you solve P?

Answer 6

I'm still a little confused :/

Answer 7

Alright, p is 7.6=8.7-1p

Answer 8

We need to isolate p

Answer 9

7,6 = 8.7 - p
7.6 - 8.7 = -p
-1.1 = -p
1.1 = p

Answer 10

so the price of one pancake is $1.1

Answer 11

Thank-you so much!! @AleshGames

Answer 12

2.9=1j+2p

2.9=1j+2∗1.1

2.9=j+2.2

0.7=j

j=0.7

Answer 13

So the solution to system of equations is :
p=1.1, j=0.7

Answer 14

We done for part B :D

Answer 15

Need part C?
