Answers:
6.99 x 20% = 1.398 rounded to 1.40. 6.99 - 1.40 = your cost of 5.59 $.
$5.60
20% times 7 = $1.40 discount
$5.59
x% • y = z
or think of it like this, if it's 20% off, then you'll be paying 80% of the price (100% of the price subtract 20%). to multiply percentages, convert to a decimal (just move the decimal two places to the left) in this case, .80 multiplied by 6.99 which equals 5.592.
That's as far as I'll go here. Hope it makes sense.
$6.99 x 0.20 = 1.398 or $1.40, since it needs to be rounded to the nearest cent. 0.20 was from 20%. (6.99 - 1.40 = 5.59) Don't forget tax based on the state you live in, it is done the same format. (5.59 x t = $$) Add the tax to the discounted fee.
