Nicola used 25% of milk she collected from her goats this morning to make cheese. If she has 8.4 quarts, how many quarts of milk did she collect this morning?

answer:

33.6 quarts

Step-by-step explanation:

Since 25% is 1/4 of a whole, to figure out said whole, simply multiply the number 8.4 by 4.

8.4*4=33.6

Nicola collected 33.6 quarts this morning.

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

answer is x<
