Hong the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the other (not both). On Friday there were 4 clients who did Plan A and 8 who did Plan B. On Saturday there were 2 clients who did Plan A and 3 who did Plan B. Hong trained his Friday clients for a total of 9 hours and his Saturday clients for a total of 4 hours. How long does each of the workout plans last?

Session A = 1.25 hours

Session B = 0.5 hours

Step-by-step explanation:

Given

Plans: A and B

Friday can be expressed as: 4A + 8B

Saturday can be expressed as: 2A + 3B

Total Time:

Friday = 9 hours

Saturday = 4 hours

Required

Determine time for each session (A and B)

The question illustrates simultaneous equation and the equations are;

Multiply the second equation by 2

Subtract this from the first equation:

Solve for B

Substitute in

Solve for 2A

Solve for A

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31

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.
