Question

I need help someone pls solve this for me

Answer 1

Answer:

The answer is below

Step-by-step explanation:

1) Let x represent the price of Tacos and y represent the price of Burrito. You where charged $4.80, hence:

2x + 2y = 4.80; Dividing through by 2:

x + y = 2.4         (1)

Your friend was charged $4.00, hence:

3x + y = 4.00     (2)        

Solving equation 1 and 2 simultaneously by subtracting equation 2 from equation 1:

2x = 1.6

x = 0.80

Put x = 0.8 in equation 1:

0.8 + y = 2.4

y = 1.60

The cost of each tacos is $0.80 and the cost for each burritos is $1.60

2) Let x represent the smaller number and y the bigger number, hence:

y - x = 16        (1)

Also:

y = 4x - 5;

y - 4x = -5       (2)

Subtract equation 2 from equation 1 to solve simultaneously:

3x = 21

x = 7

Put x = 7 in equation 1:

y - x = 16

y - 7 = 16

y = 23

The greater number is 23 and the smaller number 7
