The vendor of a coffee cart mixes coffee beans that cost $9 per pound with coffee beans that cost $5 per pound. How many pounds of each should be used to make a 75-pound blend that sells for $6.00 per pound
1 answer:
Answer:
56.25 pound of the coffee that costs $5 per pound is needed
18.75 pound of the coffee that costs $9 per pound is needed
Step-by-step explanation:
Let the number of pounds be x and y respectively
The total pounds is 75;
So;
x + y. = 75 •••••••(i)
Total cost of first type
9 * x = $9x
Total cost of second type;
5 * y= $5y
75 pound at $6 per pound; total cost of this is;
6 * 75 = $450
Thus;
9x + 5y = 450 ••••••••(ii)
From i, x = 75-y
Put this into ii
9(75-y) + 5y = 450
675 -9y + 5y = 450
4y = 675-450
4y = 225
y = 225/4
y = 56.25
x = 75 - y from i
x = 75-56.25
x = $18.75

<u>Yes the first one is correct because n squared is n with the 2 above it and adding it to three gets your first answer and then the three on the outside means to multiply so your first response is correct. </u>
A group is around 4-8 people so i would go with 4 at first. 4x32= $128 so that’s your answer, hopefully!
29 because first u add 5 then 8 3 times.
Answer:
51
Step-by-step explanation:
Plug in 3 as x into the function:
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24
g(3) = 51
The answer would be ~X > 3400~ Hope this helps Have a great day/night Feel free to ask any questions
