At a 8% off sale Lily bought a new drill and saved $17. How much did she pay for the drill? (two decimal places)


At a 16% off sale Benjamin bought a new TV for $698. What was the price of the TV before the sale. (two decimal places)

(1) If we let x be how much the drill was when Lily bought it and y the price regularly, we can make the equation x+17=y. We also know y*0.08=17. So the second equation turns into 1700/8=y so y is 212.50. Then we know x is 195.50, so lily paid $195.50 for the dill.


Hope this helps!! :)
