A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18

a+b = 12 + 18 = 30

Answer: 62.

Step-by-step explanation: The mean is the average. In order to find the average, we need to add all of the numbers up, then divide by the number of quizzes. So:

20 + 40 + 40 +40 + 60 + 60 + 60 + 60 + 80 + 80 + 80 + 80 + 100 = 800

800 / 13 = 61.5, appr. 62.

Can someone please help me with this problem?
jeka57 [31]

Answer:

110 bonus payments

Step-by-step explanation:

Yearly salary is 20,000. So in 6 years, she will get:

20,000 * 6 = 120,000

Her agent's expectation is 1,000,000 and her salary would cover 120,000

So remaining is 1,000,000 - 120,000 = 880,000

This amount will be taken from bonus payments where bonus is 8000 for every game that attracts 100+ fans. SO we divide 880,000 by 8000 to get the number of bonus payments.

880,000/8000 = 110
