Let x = cost for an apple
Then
(x+.28) = cost for an orange (given information)
:
Write an equation for the statement:
"girl buys three apples and seven oranges for $4.56."
3x + 7(x+.28) = 4.56
:
3x + 7x + 1.96 = 4.56

3x + 7x = 4.56 - 196
:
10x = 2.60
:
x =
x = .26 is the cost for an apple
then
.26 + .28 = .54 cost for an orange
:

Check solution in original equation:
3(.26) + 7(.54) =
.78 + 3.78 = 4.56
