Question

A teacher buys some pencils.

• He buys 2 pencils for each of his students.
• He buys 10 additional pencils.
• Each pencil costs $0.10.
Which equation describes the total amount of money
(y), in dollars, that the teacher spends on pencils as a
function of the number of students (x) he has?

Answer 1

y=2x(.10)

Explanation:

I think this is correct but it is 0.10 times 2 because it is 2 pencils/student and each pencil cost 10 cents. We multiply by x because we need to have 2 for each student
