The entire cost of the car ($21,345) plus the $2,500 upgrade is $21,345 + $2,500 = $23,845.
How do you know find 7% of your total in part A? Show your proportion and work. Explain your process
To find 7% of the total cost ($23,845), you can set up a proportion using the percent as a fraction in terms of 100.
Let "x" represent 7% of the total cost.
The proportion can be set up as:
7/100 = x/23,845
To solve for x, we can cross-multiply and then divide:
(7 * 23,845) / 100 = x
166,915 / 100 = x
1669.15 = x
Therefore, 7% of the total cost is $1669.15.
