How can i determine the sale price if you were given the regular price and percent of markdown

algol [13]

You would multiply the sales regular price by the percent and then subtract your answer from the regular sale price. For example, if something cost $499 and the sales price was 15% off, you would multiply 499 by 0.15 and then you would get 74.85.

There are 4,200 adults in Lakeview. Three-eighths of the adults in Lakeview do not have children. How many adults in Lakeview ha

Inessa [10]

To answer this, you first have to find 3/8 of 4200 by multiplying those two numbers.

$\frac{4200}{1} *\frac{3}{8}$

First, multiply the numerators.

4200x3=12600

Next, multiply the denominators.

1x8=8

You end up with $\frac{12600}{8}$ .

This fraction can be simplified to 1575.

All that's left is to subtract that number from 4200.

4200-1575=2625

The final answer is 2625 adults in Lakeview have children.
