Question 514999: How do i set up this equation? Every Sunday, jarrod buys a loaf of bread for 3.00. The local store has a sale on breadmakers for $73. If the bread-making supplies cost $0.71 per week, for how many weeks would jarrod have to bake a loaf of bread at home before the breadmaker starts saving him money?

You can put this solution on YOUR website!
Let w = number of weeks after he buys bread maker
Before he buys bread maker:
His cost = +3w+
After he buys bread maker:
His cost = +73+%2B+.71w+
I want to find:
+3w+=+73+%2B+.71w+
+2.29w+=+73+
+w+=+31.878+
+.878%2A7+=+6.146+
It will take about 31 weeks and 6 days
