Mrs.E bought 3 drinks and 5 sandwiches for $25.05 and Mr.E bought 4 drinks and 2 sandwiches for $13.80. How much does each drink
MAVERICK [17]

Answer:

$1.35

Step-by-step explanation:

Set up a system of equations, where d represents the price of one drink and s represents the price of one sandwich:

3d + 5s = 25.05

4d + 2s = 13.80

We can solve this by elimination by multiplying the top equation by -2 and multiplying the bottom equation by 5.

-6d - 10s = -50.1

20d + 10s = 69

Add them together:

14d = 18.9

d = 1.35
