Ben bought 8 notebooks for $24.50. Some of the
notebooks were $2.50 each, and the others were
$3.25 each. If x represents the number of least
expensive notebooks, which equation can be used
to find the number of least expensive notebooks
purchased?
A. $5.75(8 - x) = $24.50
B. $2.50(x - 8) + $3.25x = $24.50
c. $2.50x + $3.25(8 - x) = $24.50
