Let x represent the number of pounds of $10.75/lb coffee used in the mix.
.. 10.75x +3.25(100 -x) = 5.65*100 . . . . . . total cost of coffee blend
.. x(10.75 -3.25) = 100*(5.65 -3.25) . . . . . .separate x-terms from non-x terms
.. x = 240/7.5 = 32
32 pounds of $10.75/lb coffee should be used
68 pounds of $3.25/lb coffee should be used
Answer:
Step-by-step explanation:
1. Find the numerator:
2. Simplify the fraction:
Step-by-step explanation:
you have the formula and the numbers. just calculate !
cost of membership
y = 100 - 0.02x
a)
for x = 2600
y = 100 - 0.02×2600 = 100 - 52 = $48
b)
the reduction element of the cost of membership is the
"- 0.02x" part.
we want to refuse the membership costs by $41, so
0.02x = 41
x = 41/0.02 = $2,050
c)
the same as b)
just now the membership costs need to be reduced to 0.
so, that means we need to reduce by $100 !
0.02x = 100
x = 100/0.02 = $5,000
Answer:
0.4375
Step-by-step explanation:
3.5:8 is the same as 3.5/8 (ratios are like fractions)
and just use a calculator. hope this helps
Hello there!
Alright so, 100% is equal to 1, because think about it as a fraction, 2/3 is 66%, because it's not full, and 2/3 is 66%, but it's also .66(etc). So, in order to get 100% you'd have to have a 3/3.
I'm going to use 4/4. so in order to go above 100% you'd have to add more.
8/4 is 200% because it divides to 2.00
So now just add 3 more because 3/4 is 75%
11/4 is 275%
Which also divides to 2.75
2.75 is your answer, hope this helped!
