Answer:$7.50
Step-by-step explanation: make 4 boxes on a paper and put two lines in each box and you see that it is 8 in the boxes all to heather so that equals $8.00 so you can’t put a dollar in each box because if you do it will equal twelve dollars and you have to make ten dollars so you put $0.50 in each box so in each box it will be $2.50 in each box so you have to add $2.50 for times so it equals $10.00 so I added it it does add up to ten dollars so to see how much 3 bottles of water count you have to add up $2.50 3 timer and it equal $7.50
This will not factor so you can use the quadratic formula
x = [- (-3) +/- sqrt(9 - 4*5*-4) / 10
= (3 +/- sqrt 89) / 10
= 3 + 9.434 / 10 or 3 - 9.434 / 10
= 1.24 , -0.64 to the nearest hundredth
