Answer:
$39.03
Step-by-step explanation:
Joshua wants to buy five shirts:
Total cost of all shirts:
[tex]2\cdot\$10.98+\$11.50+2\cdot \$15.99=\$65.44[/tex]
All polo shirts are discounted by 20%, then the total cost of all shirts is
[tex]\$65.44\cdot (1-0.2)=\$52.352[/tex]
Joshua had a coupon in his pocket that would take an additional 30% of the shirts, then the total price will be
[tex]\$52.352\cdot (1-0.3)=\$36.6464[/tex]
He has to pay sales tax of 6.5%, so the total price will be
[tex]\$36.6464\cdot (1+0.065)=\$39.028416\approx \$39.03[/tex]
