After mixing two types of candies, the price became $3.40 per lb. The quantity of the first type of candy was 5/12 of the quantity of the second type. If the price of the first type of candy is $4.60 per lb, what is the price per pound of the second type of the candy?

the price per pound of the second type of the candy is 2.9 .

Step-by-step explanation:

Here we have , After mixing two types of candies, the price became $3.40 per lb. The quantity of the first type of candy was 5/12 of the quantity of the second type. If the price of the first type of candy is $4.60 per lb,We need to find what is the price per pound of the second type of the candy . Let's find out:

The quantity of the first type of candy was 5/12 of the quantity of the second type i.e. Quantity of candy A = 5x    quantity of candy B = 12x

We need to calculate the weighted average of the price of candies.

price of mixture = quantity of A (price of A ) + quantity of B (price of B)

Therefor , the price per pound of the second type of the candy is 2.9 .

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
