So quadratic formulas help
Answer:
1. It should be 7
2. They have $46
Step-by-step explanation:
1. You make a system of linear equations from this. So it would be y= 5x+11 where x is the number of weeks and y is the money. And the second linear equation is y=-2x+60. Then you substitute it. You make it 5x+11=-2x+60. Then you solve it normally and you got your answer but remember in this case they are asking for the x. So make sure to submit the x and not the y.
2. For this it is the same thing except they are asking for the y not the x.
