Question

Ada Mae bought a pen for $1.50 and 3 DVDs that each cost the same amount. She spent $22.50
in all. Which equation models the situation?
A, 1.5+3d=22.5
B. 3(1.5) +d=22.5
C. 3d-1.5=22.5
D. 1.5=22.5+3d

Answer 1

Items: 1 Pen: 1.50

3 DVDS: ???

Total : 22.50

It is A, 1.5+3d=22.5.

Hope this helps!!!

It is not B because you are not multiplying the number and cost of 3 DVDS by the cost of one pen.

It is not C because you are not subtracting to find the total cost. You are adding.

It is not D because 3d is part of the total cost so that option just doesn't make sense.
