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 including upgrades like floor mats and a sunroof, we need to multiply the total cost by 7% or 0.07.

Total cost including upgrades = $21,345 + $2,500 = $23,845

To find 7% of the total cost, we can set up a proportion:

7% / 100% = x / $23,845

To find the value of x, we cross multiply:

(7/100) * $23,845 = x

Now we can calculate 7% of the total cost:

(7/100) * $23,845 = $1,668.15

Therefore, 7% of the total cost including upgrades is $1,668.15.

To find 7% of the total cost, we set up a proportion by dividing 7% by 100% and setting it equal to x over the total cost. Cross multiplying, we find that 7% of the total cost is equal to $1,668.15. Therefore, when purchasing a Volkswagen Jetta with upgrades costing $2,500, Sophia will need to add 7% sales tax to her loan, which amounts to an additional $1,668.15. Thus, the total loan amount will be $23,845 including the upgrades and sales tax.
