Answer:
c = 69 and h = 51
Step-by-step explanation:
You will need two different equations here
use variable c as coffee and variable h as hot chocolate
c + h = 120
1.80c + 3.15h = 284.40
By moving variables, you can alter the first equation
h = 120 - c
Now insert this into the second equation
1.80c + 3.15(120 - c) = 284.40
Multiply
1.80c + 378 - 3.15c = 284.40
Subtract the c
-1.35c + 378 = 284.40
Subtract 378 from both sides
-1.35c = -93.6
Divide both sides by -1.35
c = 69
Then plug into the first equation
69 + h = 120
Subtract 69
h = 51
19 or 19/1
Hope this helped!
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
