Mr. Jackson orders lunches to be delivered to his workplace for himself and some coworkers. The cost of the lunch is $6.25 . There is one time delivery fee of $3.50 to deliver the lunches. What expression could Mr. Jackson use to find the cost of ordering n lunches?

$6.25n+$3.50

Step-by-step explanation:

The cost of all the lunch is $6.25 and the cost of delivery of the lunch is $3.50.

The total cost will be cost of lunch + delivery = $6.25+$3.50

= $9.75

Expression that can be used by Mr. Jackson to find the cost of ordering 'n' lunches will be $6.25n+$3.50

Note that the cost of lunch is what will be affected but not the cost of delivery since it is a one time delivery (that is the cost of delivery will not change no mater the amount of lunch ordered "at once".

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
