Trent ordered sandwiches for his friends. The veggie sandwiches cost $4 apiece and the meat sandwiches cost $5 apiece. Trent ord
ered 5 sandwiches and paid $22. How many of each type of sandwich did he order?
1 answer:
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.

a) The first integral corresponds to the area under y = f(x) on the interval [0, 3], which is a right triangle with base 3 and height 5, hence the integral is
b) The integral is zero since the areas under the curve over [3, 4] and [4, 5] are equal but opposite in sign. In other words, on the interval [3, 5], f(x) is symmetric and odd about x = 4, so
c) The integral over [5, 9] is the negative of the area of a rectangle with length 9 - 5 = 4 and height 5, so
Then by linearity, we have
