Hello, swerve78!

This is straight-forward arithmetic.
Exactly where is your difficulty?

A local retailer sells all $120 wall mirrors at 33% off.
Mitchell is bying a wall mirror and has a coupon for an additonal 15% off the sale price.
What will Mitchell pay for his mirror?

The original price of the mirror is $120.00.

The retailer gives a 33% discount.
. . \(\displaystyle 33\%\text{ of }\$120\:=\:0.33 \times \$120 \:=\: \$39.60\)

The sale price is:.\(\displaystyle \$120.00 - 39.60 \:=\: \$80.40\)

Mitchell gets another 15% off.
. . \(\displaystyle 15\%\text{ of }\$80.40 \:=\:0.15 \times \$80.40 \:=\: \$12.06\)

Therefore, Mitchell will pay:.\(\displaystyle \$80.40 - 12.06 \:=\: \$68.34\)
