Question

10. Katherine has diabetes. At each meal, she must estimate the mass in grams of carbohydrates she plans to eat, then inject the appropriate amount of insulin. Katherine needs 1 unit of insulin for 15 g of carbohydrates. Katherine's lunch has 60 g of carbohydrates. How many units of insulin should Katherine inject?​

Answer 1

Katherine needs 1 unit of insulin for 15 g of carbohydrates.

Explanation:

To find out how many units of insulin Katherine should inject for her lunch which has 60 g of carbohydrates, we can use the following proportion:

1 unit : 15 g = x units : 60 g

where x is the number of units of insulin Katherine should inject.

To solve for x, we can cross-multiply:

1 unit * 60 g = 15 g * x units

60 = 15x

x = 4

Therefore, Katherine should inject 4 units of insulin for her lunch.
