A girl buys three apples and seven oranges for $4.56. If an orange costs $0.28 more than an apple, how much does each fruit cost?
----------
# of apples is 3; price per apple is x cents ; value of three apples = 3x cents
# of oranges is 7; price per orange is "x+28"; value of oranges = 7x+196 cents
------------
EQUATION:
value + value = 456 cents
3x + 7x+196 = 456
10x = 260
x = 26 cents (price of an apple)
x+28 = 54 cents (price of an orange)
================
