Please answer quick and show work ! The price of a bicycle that ms. motyka wants to buy is $282. How much will she pay for the bicycle if there is a 4% sales tax.

$293.28

Step-by-step explanation:

We know that 282 is the 100% price tag on the bicycle. And there is a 4% tax applied to the 282. So we need to find out how much is 4% of 282.

282/100% = x/4% (we don’t know how much is 4% so its represented by X.

do a cross over where you end up with this:

282 (4) = x (100) we want to have X on its own as it represents the 4% to which we are looking for the amount in dollars. So you end up with this:

282 (4) /100 = x

solve the multiplication first and then divide.

1128/100 = x

11.28 = x

so now we know 4% of 282 is $11.28 so we add it to know how much does this person pay.

$282 + $11.28 = $293.28

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
