We are given a relationship between the carbohydrates used by a professional tennis player during a strenuous workout and the time in minutes as 1.7 grams per minute. Being C the carbohydrates in grams and t the time in minutes, the model is
The slope m of the line is the coefficient of the independent variable, thus m=1.7
The graph of C vs t is shown in the image below.
To find how many carbohydrates the athlete would use in t=40 min, we plug in the value into the equation
The average low temperature for January was 40 °F - 100%.
The average low in February was x °F - 27% lower, that is 100%-27%=73%.
Write a proportion:
Answer: the average low in February was 29.2 °F.
