The solution by the other tutor, where the $1.20 weekly allowance is divided by 7 to get a daily allowance, leads to ugly numbers.

It's far easier to convert the 25 cent daily allowance into a $1.75 weekly allowance.

Then the two allowances together are $2.95 per week; the number of weeks they need to save their allowances to save $23.60 is .

Olivia's allowance is $1.20 per week. Colton's is 25 cents per day. If they save both of their allowances together, how long will they have to save before they can get a model car set that costs $23.60?

With W being the number of weeks, the correct equation is: 1.2W + 7(.25)W = 23.60 ====> 1.2W + 1.75W = 23.6
Solve this for W, the number of weeks. You should get 8.
