WILL GIVE BRAINLIEST! Use the discount equation S = R – rR, where S is the sale price, R is the regular price, and r is the discount rate.

A toy train set with a regular price of $465 is on sale for $387. Find the markdown rate. Round to the nearest tenth of a percent.
%

The answer is 16.8%

Step-by-step explanation:

First, find the difference in the price, which is $78. You can then use that number to find the percentage by dividing the difference by the original price, then moving the decimal over to the right twice. You prove this with the discount equation. $387= $465-(16.8%*465). You will get a number similar to 387, but that is only because you are using a rounded percentage.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
