Answer : The cost of one hot hot dog and the cost of one hamburger is, $3.75
Step-by-step explanation :
Let the cost of hot dog be, 'x' and hamburger be, 'y'.
Given:
5 hot dogs and 2 hamburgers cost is, $12.00. The equation will be :
..............(1)
2 hot dogs and 5 hamburgers cost is, $14.25. The equation will be :
..............(2)
Now we have to determine the value of 'x' and 'y' by using substitution method.
............(3)
Now put equation 3 in 2, we get:
y = 2.25
Now put the value of 'y' in 3, we get:
x = 1.5
Cost of hot dog = x = $1.5
Cost of hamburger = y = $2.25
Now we have to calculate the cost of one hot hot dog and the cost of one hamburger.
Cost of 1 hot hot dog and 1 hamburger = x + y
Cost of 1 hot hot dog and 1 hamburger = $1.5 + $2.25
Cost of 1 hot hot dog and 1 hamburger = $3.75
Therefore, the cost of one hot hot dog and the cost of one hamburger is, $3.75
