Question 1095770: Solve by setting up the proper equation to describe the facts given and then carrying out the mathematical calculations to solve for the unknown variable(s).
Mary�s hourly wage is twice that of John�s. John�s and Dennis� hourly wages together total $60. If Dennis earns 1/3 of John�s rate, what does Mary make per hour?

Mary�s hourly wage is twice that of John�s

John�s and Dennis� hourly wages together total $60

Dennis earns 1/3 of John�s rate (i.e., John earns 3 times as much as Dennis)

Solving should be relatively easy.

Use the third equation to substitute in the second equation to solve for D; then use the third equation to solve for J; then use the first equation to solve for M.
