A baker needs between 40 lb and 50 lb of a flour-sugar mixture that contains ten times as much flour as sugar. What are the possible weights of flour the baker can use?

Step-by-step explanation:

Let x=amount of sugar needed

Then 10x=amount of flour needed

Now we can set up an inequality:

40<= 11x <=50 divide each term by 11

40/11<=x<=50/11 now multiply each term by 10x (amount of sugar needed)

400/11 <= 10x <=500/11 or

36.36 <=10x <= 45.45

The possible weights of flour the baker can use is greater than or equal to 36.36 lb and less than or equal to 45.45 lb

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
