A group of students goes out to lunch. If three have burritos and four have tacos, the bill will be $19.00 If five have burritos and three have tacos, the bill will be $25.25. Find the price of each taco and burrito

burritos cost $4

tacos cost $ 1.75

Step-by-step explanation:

let b represent the price of burritos

let t represent the price of tacos

3b + 4t = 19

5b + 3t = 25.25

multiply the first equation by -3 and second by 4 to eliminate t

-3(3b + 4t = 19)

4(5b + 3t = 25.25)

-9b - 12t = -57

20b + 12t = 101

add both equations

11b  = 44

11       11

b = 4

substitute b = 4 into any equation to find the price of tacos

3b + 4t = 19

3(4) + 4t = 19

12 + 4t = 19

-12          -12

4t = 7

4    4

t = 1.75

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
