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?

Respuesta :

Manetho

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:

40
