Question

The employees at a bank ordered 2 turkey sandwiches and 4 salads from a local deli. The total cost for the order was $23. If a salad costs $1 less than a turkey sandwich, what is the cost of a turkey sandwich and the cost of a salad?

Answer 1

Answer:

Cost of turkey sandwich is $4.50 and cost of salad is $3.50

Step-by-step explanation:

Let cost of 1 turkey sandwich be $t and cost of 1 salad be $s.

2t + 4s = 23 --(1)

s + 1 = t

s = t - 1 --(2)

Sub (2) into (1):

2t + 4(t - 1) = 23

6t - 4 = 23

6t = 27

t = 4.5

sub t = 4.5 into (2):

s = 4.5 - 1

s = 3.5

therefore, cost of turkey sandwich is $4.50 and cost of salad is $3.50
