A. The total car price plus upgrades is $21,345 + $2,500 = $23,845.
B. To find 7% of the total in part A, we can use the proportion: 7/100 = x/$23,845, where x represents the amount of the sales tax. To solve for x, we can cross multiply: 7 * $23,845 = 100x. This gives us 167,915 = 100x. Dividing both sides by 100, we find that x = $1,679.15. Rounding to the nearest whole number, the sales tax is $1,679.
