Question

The mathville cafeteria sells eggs and toast at a fixed price. Yesterday, Rick ordered two eggs and one piece of toast and was charged $1.50. Today he ordered two eggs and three pieces of toast and was charged $2.30. Find the cost of each item.

Answer 1

E=egg, t=toast

2e+t=1.50
2e+3t=2.30
2t=80, toast=40

2e+40=1.50
2e=110
1egg=55

Answer 2

Answer:

the eggs are $0.55 and the toast is $0.40

Step-by-step explanation:

1. 2.30 - 1.50 = 0.80

2. 0.80 ÷ 2 = 0.40 (the cost of the toast)

3. 1.50 - 0.40 = 1.10

4. 1.10 ÷ 2 = 0.55 (the cost of the eggs)
