Question

George paid $2.75 for 4 granola bars and 1 apple. Addi paid $2.25 for 2 granola bars and 3 apples. Find the cost of each granola bar and apple.

(Solve using system of linear equations)

Answer 1

Answer: The cost of one granola bar is $0.60 and the cost of one apple is $0.35

Step-by-step explanation: Cost of one granola bar = x

Cost of one apple = y According to the given statement;

4x+y=2.75 Eqn 1

2x+3y=2.25 Eqn 2

Multiplying Eqn 2 by 2

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 5

Putting y=0.35 in Eqn 2

Dividing both sides by 4

The cost of one granola bar is $0.60 and the cost of one apple is $0.35
