To find the mean, aka average, we must add all the values of the table, then divide that sum by the number of values
7.50
25% also equals 1/4 so divide 130.00 by 4 which equals 32.50
subtract 32.50 from 130.00 which equals the cost, 97.50
97.50 minus 90$ is 7.50, therefore that is the answer
1. 1/2 2. 3 3. x=-1.5x+7.5
A is unsolvable because 4=0.
B can be solved.
C is infinite
Answer:
15 times 32 times 6 is 2880
16 times 6 times 2 is 192
2880 plus 192 is 3074
D) 3074
