Answer: $34.75
Step-by-step explanation:
n= 6.25x+3.50
n=6.25(5)+3.50
n=31.25+3.50
n=34.75
The expression which Mr. Jackson use to find the cost of ordering n lunches is $6.25n+$3.50 and the cost of delivering 5 lunches is $34.75.
How to write algebraic expression?
Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic expression-
- Identify all the factors of the expression.
- Assume a variable for the changing values.
- Put a coefficient for the variable, if there is any rate of change of variable.
- Use constant numbers for the fixed values.
Mr. Jackson orders lunches to be delivered to his workplace for himself and some coworkers.
The cost of each lunch is $6.25. Let there is total n workers at the workplace inculding Mr. Jackson. Thus the cost of lunch of n person is,
[tex]6.25\times n\\6.25n[/tex]
Now, there is also a one-time delivery fee of $3.50 to deliver the lunches. Thus, the cost become,
[tex]6.25n+3.50[/tex]
Thus, the expression used by Mr. Jackson is $6.25n+$3.50. To find the total cost of delivering 5 lunches, put the n=5 in the above expression as,
[tex]6.25(5)+3.50\\31.25+3.50\\34.75[/tex]
Thus, the cost of delivering 5 lunches is $34.75.
Hence, the expression which Mr. Jackson use to find the cost of ordering n lunches is $6.25n+$3.50 and the cost of delivering 5 lunches is $34.75.
