So if one tray of vegetarian sandwiches cost $10, that means that 10 trays of vegetarian sandwiches would cost $100 (10x10)
Going back to the first order, if we know that 10 trays of vegetarian sandwiches costs $100, then we can subtract that from our overall of $149, leaving us with the cost of 7 trays of club sandwiches
$149 - $100 = $49
therefore, $49 is the cost of 7 trays of club sandwiches
to find the cost of 1 tray, we need to divide $49, by 7
$49 / 7 = $7
therefore, one tray of club sandwiches costs $7 and one tray of vegetarian sandwiches costs $10
hope that was helpful :)
(-3/2,11/2) is the midpoint
Answer:
27 and 29
Step-by-step explanation:
let A and B the expected numbers
assuming B = A + 2, the problem can be written as follows
¼(A + A + 2) = 14
4*¼(A + A + 2) = 4*14
(A + A + 2) = 56
2A + 2 = 56
A + 1 = 28
A = 27
B = 27 + 2 = 29
