Asalesperson at an electronic store is given a choice of two different compensation plans. plan a pays him a weekly salary of $250 plus a commission of $25 for each stereo sold. plan b offers no salary but pays $50 commission on each stereo sold. how many stereos must the salesperson sell to make the same amount of money with both plans?

10 stereos must the salesperson sell to make the same amount of money with both plans.

Step-by-step explanation:

Let the Number of stereo sold = x

According to Plan A

250 + 25X

According to Plan B

50X

According to given condition

250 + 25X = 50X

250 = 50X - 25X

250 = 25X

X = 250/25

X= 10

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."

good luck on ur quiz test or homework. have a good day : )
