the cost of a taco and the cost of a small glass of milk are $1.05 and $0.95 respectively
Step-by-step explanation:
This may be computed through the establishment of 2 linear equations. This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations. It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation
.
Let the cost of a breakfast taco be a and that of a small glass of milk be r. Then given that the cost for a breakfast taco and a small glass of milk is $2.10
It means that
a + r = 2.1
If the cost for two tacos and three small glasses of milk is $5.15 ,then
2a + 3r = 5.15
2a + 2r = 4.2 ( the first equation multiplied by 2)
