Answer:
The predicted GPA is then y = 0.149(15) + 0.89 = 3.125
Step-by-step explanation:
Although you don't specifically say so, the equation you provide here is probably a "best fit" equation based upon data: GPA versus number of hours of study per week.
Here, y = 0.149x + 0.89 and the number of study hours of interest is 15.
The predicted GPA is then y = 0.149(15) + 0.89 = 3.125

Answer: 78.54
Step-by-step explanation:
To solve for the percentage increase of the cost of jacket, calculate first for the increase, divide it by the original price and then multiply by 100%. This is shown below.
% increase = ((98.60 - 85) / 85) x 100%
% increase = 16%
Thus, the price of the jacket increased by 16%.
