Answer:
For 4 sandwich's, you can pay half the price ($16) to eat at Dino's diner then at Carlas Cafe ($32).
Explanation:
Note that you are trying to solve for the amount per cost for 1, 2, 3, & 4 sandwiches. To solve, multiply the amount each sandwich costs to the amount of sandwiches you are trying to buy.
Dino's diner charges $4 for each sandwich.
If you buy 1 sandwich: (1 x 4 = $4), the cost is $4.
If you buy 2 sandwich: (2 x 4 = $8), the cost is $8.
If you buy 3 sandwich: (3 x 4 = $12), the cost is $12.
If you buy 4 sandwich: (4 x 4 = $16), the cost is $16.
Carlas cafe charges $8 for each sandwich.
If you buy 1 sandwich: (1 x 8 = $8), the cost is $8.
If you buy 2 sandwich: (2 x 8 = $16), the cost is $16.
If you buy 3 sandwich: (3 x 8 = $24), the cost is $24.
If you buy 4 sandwich: (4 x 8 = $32), the cost is $32.
