Answer:
Answer b = $ 2.25 dollars
s = $ 1.75 dollars
Please see how to do, it is good to know the answers but if you know how to solve it thats even better!!
Step-by-step explanation:
Let : s = soft tacos
b = burritos
Step 1: 11.50 = 4s + 2b
12.00 = 3s +3b
Step 2: Solve using subtraction
12 =3s + 3b
-1 (11.50 = 4s + 2b) _ times by -1 so you can subtract
-11.50 = -4s -2b _ once you do this bring the other equation
12.00 = 3s + 3b _ then subtract/ add
_____________+__
0.50 = -s + b _ add s to both sides
s + 0.50 = b _ now you can plug in b into the original equation
12.00 = 3s + 3(s + 0.50) _distribute the 3 to the s and 0.50
12.00 = 3s + 3s + 1.5 _ add like terms
12.00 = 6s + 1.5 _ - 1.5 on both sides
-1.5 -1.5
10.5 = 6s _ divide by 6 to isolate s
1.75 = s _ plug it in to find b
11.5 = 4(1.75) +2b
11.5 = 7 + 2b _ subtract 7 on both sides
4.5 = 2b _ divide by 2 on both sides
2.25 = b
Answer b = $ 2.25 dollars
s = $ 1.75 dollars
