Question

Write and simplify the equation you would use to solve the problem below. Scott has a jar of quarters and dimes. If there is $4.15 in the jar, and there are 4 dimes, how many quarters are in the jar?
A. x(25 + 10) = 415
B. 25x + 40 = 415
C. 25x + 10 = 415
D. 4 * 10x + 25x = 415

Answer 1

The correct option is: B. 25x+40=415 
 The explanation is shown below:
 
 1. You have that:
 
 - There is $4.15 in the jar.
 -There are 4 dimes in the jar.
 
 2. Therefore:
 
 1 quarter=25 cents
 4 dimes=40 cents
 $4.15=415 cents
 
 3. Then, you have that the equation you would use to solve the problem and to calculate how many quarters are in the jar, is:
 
 25x+40=415
