Question

Mrs. Johnson is buying every student in her math class a pencil and an eraser. Each pencil costs 25 cents and each eraser costs 15 cents. If x represents the number of students in Mrs. Johnson’s class, what is the equation for this

Answer 1

Total amount spent by Mrs. Johnson : T(x) = 25x + 15x

Explanation:

Cost of each pencil = 25 cents

Cost of each eraser = 15 cents

x is the number of students in the class.

So, total cost of erasers purchased= 15x

and total cost of pencils purchased = 25x

Hence, Mrs, Johnson Spends total amount on eraser and pencil = 25x + 15x

or, total amount spent by Mrs. Johnson: T(x) = 25x + 15x
