Question

At a bake sale, the golf team sold all 50 cupcakes for $1.50 each. They sold almost all of the 100 cookies for $1.00 each. The team also received donations from 7 people averaging $4.25 per donation. Determine the total amount of money the golf team collected from the bake sale with a reasonable level of accuracy.

Answer 1

Explanation:

The total sales is $204.75, but the problems states ". . almost 100 cookies." It also states the donations are an average, but I'll assume their calculation was done correctly and accept it as an actual amount.

We know that we actually sold less than 100 cookies. Thus the value of $204.75 is too high, since it assumes 100 cookies. We don't know what the exact number is, but it has to be $203.75 or less, if we assume 99 cookies, one less than 100.

Therefore, I believe that we can only say that the total was under $203.75. Depending on how you want to treat "almost," it could be anywhere from 90 - 99 cookies, in my mind. If the person speaking "almost" has a habit of overstating things, then it is likely even less than that. [e.g., "I almost caught the record-breaking fish" doesn't invoke confidence.]
