Rhonda bought five shirts from a
store and had $10 left. if she had only
bought three shirts, she would have
had $24 left.
if each shirt costs the same, which of
the following equations could be used
to determine x, the cost of each shirt,
in dollars?
a 10 - 5x = 24 - 3x
b 5x + 3x = 10 + 24
c 10 + 5x = 24 +3x
d 5 + 10x = 3 + 24x
