PLEASE HELPPP !!!
baherus [9]

Answer:

<em>1) 6%</em>

<em>2) $1,689.35</em>

Step-by-step explanation:

1) Given the following

Sales tax = $64.80

Price of the computer = $1080

Required

rate of sales tax

Using the expression

x% of 1080 = 64.80

x/100 * 1080 = 64.80

10.80x = 64.80

x = 64.80/10.80

x = 6%

<em>Hence the rate of sales tax is 6%</em>

<em></em>

2) Given the following

Price of the car = $25,990

Tax rate = 6.5%

Sales tax charged = 6.5% of $25,990

Sales tax charged = 6.5/100 * 25,990

Sales tax charged = 6.5 * 259.9

Sales tax charged = $1,689.35

<em>hence the sales tax being charged is $1,689.35</em>
