To calculate the grade point average you have to sum all the points of each course multiplying the hours and then diveded by the total number of hours she did.

She earned a grade B in her 4 hour topology course, so she has 3*4 points.

In her 11 hour gouvernment course, she earned a grade D, so she has 1*11 points. In the 2 hour biology course she earned a grade D, so she has 1*2 points and in her 3 hours studio art course she had also a grade D, so she has 1*3 points

She has done 3+2+11+4 hours of subjects=20.

The total average is (3*4+1*11+1*2+1*3)/20=28/20=1.4

Mama L [17]

Answer:

$91.75

Step-by-step explanation:

Jessica is paid:

$0.45 per basket for the first 100 baskets picked;
$0.50 per basket for all baskets over 100 picked.

1st day:

Jessica picked 65 baskets of oranges (less than 100)

Jessica is paid $65\cdot \$0.45=\$29.25$

2nd day:

Jessica picked 135 baskets of oranges (35 more than 100)

Jessica is paid $100\cdot \$0.45+35\cdot \$0.50=\$45+\$17.50=\$62.50$

Altogether Jessica is paid

$\$29.25+\$62.50=\$91.75$
