Joel opened a checking account. His bank charges him a service fee of $4.95each month. Assume y = total cost of having the account and x = number of months.

Answers

y= x • $4.5
it needs to be 20 characters so here’s this ndnsoxid

Final answer:

The subject of this question is Mathematics and the grade level is High School. The relationship between the number of months and the total cost of having the account can be represented by the formula y = 4.95x, where y is the total cost and x is the number of months.

Explanation:

The subject of this question is Mathematics

Joel's monthly service fee is $4.95, therefore, each month the total cost of having the account increases by $4.95
In terms of variables, let x be the number of months and y be the total cost of having the account
The relationship between x and y can be expressed as y = 4.95x, where 4.95 represents the monthly service fee and x represents the number of months

Thus, the formula y = 4.95x represents the relationship between the number of months and the total cost of having the account.
