Answer:
The medical doctor prescribed 0.35 ml of insulin per day.
Step-by-step explanation:
To find out how many millimiters of insulin was prescribed we need to find out how many units we have to took. The doctor prescribed two does of 15 units and 20 units, so the total of units for the day is the sum of the two in this cas 15 + 20 = 35 units. Now we can use a proportion rule, if we have 100 units for 1 ml in 35 units we will have an x amount of ml:
x = 35/100 = 0.35 ml
The medical doctor prescribed 0.35 ml of insulin per day.
Yes, as x(y) increase when y(x) increases , they are proportional.
