Answer:
$0.80
Step-by-step explanation:
Find the unit rate
1 apple costs ?
1.20/6 = cost of 1 apple
1 apple = $0.20
4 apples = $0.20 * 4
4 apples = $0.80
6apples = 1.20$
4apples = x$
x$*6apples = 1.20$*4apples
x$ = 1.20$*4apples / 5apples
x = 0.8$
4apples = x$
x$*6apples = 1.20$*4apples
x$ = 1.20$*4apples / 5apples
x = 0.8$
