Hi,
Please give me a hint on how to setup the equation for this word problem.
Mickey and Minnie are on different mobile plans.
Minnie pays 55 cents a call and 3 cents a minute
Mickey pays 51 cents a call and 4 cents a minute
If a call costs the same on both plans, how long is the call?
My first guess is
.55 + .03x = .51 + .04x
And then solve for x?
