Algebra Difficulty 2.0 Junior Find the answer Canada

A computer software retailer has 1200 copies of a new software package to sell. From past experience, she knows that:
• Half of them will sell right away at the original price she sets,
• Two-thirds of the remainder will sell later when their price is reduced by 40%, and
• The remaining copies will sell in a clearance sale at 75% off the original price.
In order to make a reasonable profit, the total sales revenue must be \$72 000. To the nearest cent, what original price should she set?

(A) $60.01\$60.01 (B) $75.01\$75.01 (C) $79.13\$79.13 (D) $80.90\$80.90 (E) $240.01\$240.01
