Answer:
Selling rice is $10.00
Step-by-step explanation:
The manager put what the markup of $3.00 was to be added onto what the item cost.
Answer:
168 = L + 2W
And you want to maximize LW.
Which means you want to maximize W (168 - 2W), or 168W - 2W^2.
To maximize that, the derivative must go to zero.
0 = 168 - 4W, or W = 42. And L = 84. Done. :-)
Step-by-step explanation:
Answer:
11/4 = 5/4
If you need 5/4 cups of sugar to make 20 cookies or in other words,
For 20 cookies you need 5/4 cups of sugar then
for 14 cookies you will need: 14 * (5/4)/20 = 7/8 cups of cookies
if you like a very sweet cookies then you can add a bit more sugar to make it 1 full cup of suger
When you translate the problem into mathemathical equation it will give
x is the number of 1$
y is the number of 5$
z is the number of 10$
2y=z+z
x+5y+10z=893
then you solve the equation and get the answers.
