Checking account B is better. You can find the answer by making two equations. For A the equation can be y=$6.50x+25 and for B it would be y=$8.50+16. Substitute 4 in to the X spot and you will find A equals $51, while B equals $50.

Answer:

Checking account B

Explanation:

Given :

Checking account A charges a monthly service fee of $25 and a wire transfer fee of $6.50.

Checking account B charges a monthly service fee of $16 and a wire transfer fee of $8.50.

To Find : Checking account is the better deal if four wire transfers are made per month.

Solution :

Let x be the total no. of wire transfer in a month

Let y be the total cost per month.

For checking account A

A monthly service fee = $25

A wire transfer fee = $6.50.

A wire transfer fee of x wires = $6.50x

So, Total cost y of checking account A = monthly service fee + wire transfer fee of x wires

⇒ y = $25+$6.50x -----(a)

Since we are given that four wire transfers are made per month

So, put x = 4 in (a)

⇒y = $25+$6.50*4

⇒y = $51

Thus,Total cost y of checking account A = $51

For checking account B

A monthly service fee = $16

A wire transfer fee = $8.50.

A wire transfer fee of x wires = $8.50x

So, Total cost y of checking account B = monthly service fee + wire transfer fee of x wires

⇒ y = $16+$8.50x ----(b)

Since we are given that four wire transfers are made per month

So, put x = 4 in (b)

⇒y = $16+$8.50*4

⇒y = $50

Thus, Total cost y of checking account B = $50

Since checking account A total cost is $51 and checking account B total is $50

So, account B is the better deal as its total cost is less than total cost of account B
