(6 + 5i)(4 + 7i) = 24 + 42i + 20i + 35i²
= 35i² + 62i + 24
The product of 6+5i and 4+7i is 35i² + 62i + 24.
From the problem,
x is the number of quarts of Tuscan sauce and
y is the number of quarts of marinara sauce
We add the following variables
t as the number of tomatoes
c as the number of cups of oil
z is the total profit
The constraints are the following
x = 6t + c
y =5t + 3c
6t + 5t ≤ 45
c + 3c ≤ 10
z = 4x + 5y
where z is to be maximized
Whats the rest of the question?
I think the answer to that is 1 guest because it said charges guest which means only 1 person is charged
