Trent ordered 3 veggie sandwiches and 2 meat sandwiches.
Step-by-step explanation:
Given,
Total sandwiches ordered = 5
Total amount spent = $22
Cost of one veggie sandwich = $4
Cost of one meat sandwich = $5
Let,
x be the number of veggie sandwiches
y be the number of meat sandwiches
According to given statement;
x+y=5 Eqn 1
4x+5y=22 Eqn 2
Multiplying Eqn 1 by 4

Subtracting Eqn 3 from Eqn 2

Putting y=2 in Eqn 1

Trent ordered 3 veggie sandwiches and 2 meat sandwiches.
