1 answer:
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
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 3
Putting x=8.49 in Eqn 1
One burrito salad costs $8.49 and one tortilla salad costs $3.59
