Sagot :
let rolls be x
chicken: 4*x= 4x
rolls: x
broccoli: 2*x= 2x
4x+x+2x=7x
7x=$21
x= $21/7
= $3
she spent $3 on the rolls
chicken: 4*x= 4x
rolls: x
broccoli: 2*x= 2x
4x+x+2x=7x
7x=$21
x= $21/7
= $3
she spent $3 on the rolls
Using a system of equations, it is found that she spent $3 on rolls.
---------------
This question is solved using a system of equations, considering that:
- The rolls cost z.
- Broccoli cost y.
- Chicken cost x.
---------------
- Total of $21, thus:
[tex]x + y + z = 21[/tex]
- The cost of chicken is 4 times as the cost of rolls, thus, [tex]x = 4z[/tex]
- The cost of broccoli was twice the price of rolls, thus [tex]y = 2z[/tex]
---------------
Solving for z, we find how much she spent on rolls, thus:
[tex]x + y + z = 21[/tex]
[tex]4z + 2z + z = 21[/tex]
[tex]7z = 21[/tex]
[tex]z = \frac{21}{7}[/tex]
[tex]z = 3[/tex]
She spent $3 on rolls.
