Equate real part and imaginary part:
LHS:
real part -- 12
imaginary part -- 5y
RHS:
real part = 4x
imaginary part = 25
Equating::
12 = 4x
x = 12/4
x = 3
Again:
5y = 25
y = 25/5
y = 5
So,
x = 3
y = 5
I think the average would increase by $1,650. 5% of 33000 is 1,650. So the the total amount would increase by that.
Answer:
Bob is paying more for the actual steak
Step-by-step explanation:
we know that
Maria selects a cut that costs $19.98 per pound (Maria's steak is all meat)
Bob’s selection costs $13.98 per pound (Bob’s cut of beef is 1⁄3 bone and fat)
so
Bob's cut is 2/3 all meat
Find the unit rate of Bob's cut for all meat
therefore
Bob is paying more for the actual steak
