Answer:

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 y=0.05x+2.

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 y=0.10x+1.5.

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 $)                                                       y=0.05x+2                            y=0.10x+1.5

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,

<h3>The 11th check will make Bank A cheaper.</h3>
