According to the problem, the cost is 35% off the price of $679. First, we have to find 35% of 679.
[tex]0.35(679)=237.65[/tex]Then, we subtract from the price
[tex]679-237.65=441.35[/tex]Now, we have to take off 15%, so let's find 15% of 441.35
[tex]0.15\cdot441.35=66.20[/tex]Then, we subtract
[tex]441.35-66.20=375.15[/tex]
