rio buy 4 apples and 2 plums for 1.96$
write down a pair of simultaneous equations and solve them to find the cost of 1 apple and the cost of 1 plum

Answer 1

1 plum = $0.38 and 1 apple = $0.30

Explanation:

The simultaneous equations would be :

1. 7a + 3p = $3.24

2. 4a + 2p = $1.96 ( we will half this equation to make it easier)

2a + p = $0.98
