Answer:
$7.50 multiplied by 12 = $90.00
Step-by-step explanation:
$90 (assuming 1 book per camper)
We are not told the number of books per camper.
If each camper gets 1 book, then since there are 12 campers, then there are 12 books.
12 * $7.50 = $90
(BTW, the word "spended" does not exist. The correct word is "spent.")
If you did it three times it would be 4 1/2. If you wanted to make it at least 4 3/4 then you would need to do 1 1/2 4 times.
Answer:$290
$181.25/5=$36.25x8=$290
K - 12 = X
Can't really, it's an expression.
