Answer:
Step-by-step explanation:
As given ,
-5*(a+3) =-55
(-5*a)+(-5*3)= -55
-5a-15= -55
-5a= -55 +15
-5a = -40
a = 8
One burrito salad costs $8.49 and one tortilla salad costs $3.59
Step-by-step explanation:
Let,
x be the cost of one burrito
y be the cost of one tortilla
According to given statement;
2x+y=20.57 Eqn 1
3x+3y=36.24 Eqn 2
Multiplying Eqn 1 by 3
![3(2x+y=20.57)\\6x+3y=61.71\ \ \ Eqn\ 3](https://tex.z-dn.net/?f=3%282x%2By%3D20.57%29%5C%5C6x%2B3y%3D61.71%5C%20%5C%20%5C%20Eqn%5C%203)
Subtracting Eqn 2 from Eqn 3
![(6x+3y)-(3x+3y)=61.71-36.24\\6x+3y-3x-3y=25.47\\3x=25.47](https://tex.z-dn.net/?f=%286x%2B3y%29-%283x%2B3y%29%3D61.71-36.24%5C%5C6x%2B3y-3x-3y%3D25.47%5C%5C3x%3D25.47)
Dividing both sides by 3
![\frac{3x}{3}=\frac{25.47}{3}\\x=8.49](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B25.47%7D%7B3%7D%5C%5Cx%3D8.49)
Putting x=8.49 in Eqn 1
![2(8.49)+y=20.57\\16.98+y=20.57\\y=20.57-16.98\\y=3.59](https://tex.z-dn.net/?f=2%288.49%29%2By%3D20.57%5C%5C16.98%2By%3D20.57%5C%5Cy%3D20.57-16.98%5C%5Cy%3D3.59)
