Bank a charges a monthly service fee of $2.00 and a per check fee of 0.05, while bank b charges a monthly service fee of $1.50 and a per - check fee of $0.10 which of these number of monthly checks will cause bank a to charge less in fees bank b

Thus, the 11th check will make Bank A cheaper.

Step-by-step explanation:

Let the number of checks = x.

Bank A charges monthly fee of $2 and per-check fee of $0.05.

The equation representing the account charge (y) of Bank A is .

Similarly, Bank B charges monthly fee of $1.50 and per-check fee of $0.10.

The equation representing the account charge (y) of Bank A is .

Substituting the values of x= number of checks, the table for the bank charges of each bank is,

Number of checks (x)          Bank A (in $)                       Bank B (in $)                                                                                   

0                                                2                                          1.5

1                                                 2.05                                     1.6

2                                                2.1                                         1.7

3                                                2.15                                       1.8

4                                                 2.2                                       1.9

5                                                2.25                                       2

6                                                  2.3                                      2.1

7                                                 2.35                                     2.2

8                                                   2.4                                     2.3

9                                                 2.45                                     2.4

10                                                  2.5                                     2.5

11                                                 2.55                                     2.6

So, from the table, we see that,

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
