Answer:

  360

Step-by-step explanation:

Sam obtains a "contribution margin" of $0.50 -0.25 = $0.25 per cookie. That will cover the cost of baking supplies when he sells ...

  $90 / ($0.25/cookie) = 360 cookies

Sam needs to sell 360 cookies before he can start making a profit.

_____

If you like, you can find Sam's break-even point by equating revenue and cost. The is the number of cookies Sam must sell for a profit of 0, that is, for non-negative profit.

  P = R - C

  0 = R - C

  R = C

  0.50n = 90 +0.25n

  0.25n = 90 . . . . subtract 0.25n

  n = 90/0.25 = 360 . . . .divide by the coefficient of n

You may notice this is similar to our description above.

Juliette [100K]

Answer:

32%

Step-by-step explanation:

Given

Cost of Crockpot = $125

Coupon = $40

Coupon applies on items greater than $100

Percent saved if coupon is applied.

If she applies coupon on the Crockpot, then she'll be saving $40.

Percent Savings = Amount Saved / Total Amount

Percent Savings = $40/$125

Percent Savings = 0.32

Convert to Percentage

Percent Savings = 0.32 * 100%

Percent Savings = 32%.

Hence, she'd save 32% if she applies the coupon of $40 on the Crockpot
