A7 in, medium -angle grinder is on sale for $79.80 and is marked as being 40% off. What was the original list price?

Step 2:

The details of the solution are as follows:

40% off means that, we are working with 60 % of the original price, then we have that:

`\begin{gathered} From\text{ the question, we can see that:} \\ \text{ \$ 79.80 --- 60\%} \\ x\text{ -------100\%} \\ cross-multiply,we\text{ have that:} \\ 60x\text{ = 79.80 x 100} \\ 60x\text{ = 7980} \\ Divide\text{ both sides by 40, we have that:} \\ x\text{ = }(7980)/(60) \\ \text{x = \$ 133} \end{gathered}`
