A sled sells for $40 is on sale for $28. By what percent is the price reduced?

The price is reduced by 30 percent

Step-by-step explanation:

the price was reduced by 30 percent how I got the answer was taking by taking 100 dividing it by 40 then multiplying it by the new number 28, with this it gives you 70 and that means it is 70 percent of the whole answer 40 so that's how you get 30 percent as the reduction.

40-28-12

12/40 = 0.3

0.3 = 30%
