Henry wants to buy a new table saw for his carpentry shop. He has saved $360 which is 2/3 of the price of the saw. How much does

Tema [17]

If 360 is 2/3 of the full price on a saw then your equation should look like this:

$360=\frac{2}{3} *x$

x is your unknown full price of the saw. Just solve for x now.

$360=\frac{2}{3} *x\\ \\ x=\frac{3}{2} *360=540$

This means that the full price is $540.

Hope this helps!
