Question

the expression 15n + 12n + 100 rersents the total cost in dollars for skis, boots and a lesson for n skiers. simplify the expression 15n + 12n +100, then find the total cost for 8 skiers.

Answer 1

15n + 12n + 100
combine like terms (15n and 12n)
27n + 100
27(8) + 100
216 + 100
316

total cost: $316

Answer 2

$316.

Explanation:

The terms that have n can be operated:

15n +12n + 100 = 27n +100. Then, we have that

total cost = 27n +100 for n skiers. So, for 8 skiers we have

total cost = 27(8) +100 = 216 + 100 = 316.

Then, the total cost of 8 skiers is $316.
