We find the area of a rectangle by multiplying the lengths of both the sides <em>(length and width).</em>
One side given is
Another side given is
Multiplying these 2 will give us the expression for the area of the rectangle <em>(we use distributive property given by in this problem to multiply)</em>
Area =
<em>Now combining like terms and rearranging, we have:</em>
Step-by-step explanation: First do 3,500 divided by 10 to find the cost of each shirt. Second subtract 7 from 10 which is 3. Then divide 3 by ten because you always divide by the amount being paid for. So 3 divided by 10 is .3 then multiply .3 by 100 which is 30 and that is your percent markup
