Answer:
90 pounds, 210 pounds
Step-by-step explanation:
<u>Given</u>:
A storekeeper wants to mix two types of flour to get 300 pounds, so he can sell it by 2.50$ per pound.
He uses flour worth $2.40 a pound with another flour worth $3.00 a pound.
<u>Question</u>:
How many pounds of each does he use?
Solution:
Let pounds of one type of flour mixed =
Then pounds of another type of flour mixed =
Cost of 1 pound of one type of flour = $2.40
Cost of pounds of one type of flour =
<u>Similarly</u>,
Cost of 1 pound of another type of flour = $3
Cost of pounds of another type of flour =
Cost of mixed flour per pound = $2.5
Total cost of mixed flour per pound = $2.5 300 = $750
Cost of pounds of one type + Cost of
pounds of another type = $750
Pounds of one type of flour mixed = = 90 pounds
Pounds of another type of flour mixed = = 300 - 90 = 210 pounds
Thus, 90 pounds of one and 210 pound of another type of flour mixed.
Answer:
Explanation:
<u>Equation:</u>
This is a decaying exponential function, because the exponent is negative.
Then, the larger the value of t (number of months), the smaller A (the number of hectares).
The factor 1,562.5 is the initial number of hecares, when t = 0.
You must find the value of t when A equals 500, thus solve the equation:
Divide both sides by 1,562.5
Take base-10 logarithms on both sides:
Note that the logarithm of a number decimal number is negative number, thus t will be positive. When you compute that, it is about 4.9 months.
