I think this is it I did this when I was in 5th grade so I don't remember that much might wanna check with an adult.
Sam would have to pay $510 to buy 5 shirts and 2 suck belts.
Step-by-step explanation:
Let,
Cost of one shirt = x
Cost of one belt = y
According to given statement;
6x+4y = 660 Eqn 1
x = 3y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
![6(3y)+4y=660\\18y+4y=660\\22y=660](https://tex.z-dn.net/?f=6%283y%29%2B4y%3D660%5C%5C18y%2B4y%3D660%5C%5C22y%3D660)
Dividing both sides by 22
![\frac{22y}{22}=\frac{660}{22}\\y=30](https://tex.z-dn.net/?f=%5Cfrac%7B22y%7D%7B22%7D%3D%5Cfrac%7B660%7D%7B22%7D%5C%5Cy%3D30)
Putting y=30 in Eqn 2
![x=3(30)\\x=90](https://tex.z-dn.net/?f=x%3D3%2830%29%5C%5Cx%3D90)
One shirt costs $90 and one belt cost $30.
Price of 5 shirts = 90*5 = $450
Price of 2 belts = 30*2 = $60
Total = 450+60 = $510
Sam would have to pay $510 to buy 5 shirts and 2 suck belts.
