Step 1 of 2: Determine the cumulative frequency for the fourth class.

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

umm you say your want to . but you do know that this is the mathematics.
