Question

A school group is going on a trip to a museum. Admission is $10 per student. Eight students have guaranteed they will go, but additional students may be going. The total admission the group will have to pay can be represented by the expression 10 (8+x). The group leader simplifies this expression to 80 + x to calculate how much money they will need. Is this correct? If 6 additional students go, will they have enough money to cover the admission cost?

Answer 1

It is simplified incorrectly and they will need more money.

Explanation:

1. To simplify 10 (8 + x), multiply 8 by 10 and x by 10. You should get 80 + 10x.

2. I didn't fully work it out, sorry :( but I know they wouldn't have enough.

Answer 2

At is incorrect also they would not have enough money
