Step-by-step explanation:
x + y = 985
2.95x + 9.95y = 7343.75
-2.95x - 2.95y = -2905.75
7y = 4438
y= 634 steak sandwiches
x + 634 = 985
x = 351 hot dogs

Answer:
$42.58
Step-by-step explanation:
You would multiply the price of the item (45.79) by the percentage as a decimal (0.07) and subtract the product.
in this case:
