Question

I don't understand how to do percentages please explain​

Answer 1

Answer: $60.7915

Explanation:

think of percents as a portion of something

if Dave has to pay 6% tax on something + 1% tax he will pay 7% tax.

This means he will pay 7% of 78.95.

In multiplication 'of' means multiply.

just use this as a rule so 7% × 78.95 will be the amount of tax he has to pay

0.07 × 78.95 = $5.5265

However, he has a 30% off coupon

so,

30% × 78.95 will give the amount he saves

.3 × 78.95 = $23.685 saved

now lets find the actual amount he saves with his coupon after taxes:

$23.685 - $5.5265 = $18.1585 saved

we can subtract this amount by the price and we will have the amount Dave has to pay for the jeans:

$78.95 - $18.1585 = $60.7915

⇒ $60.7915 is the price Dave pays

rounding we get $60 and 79 cents

Answer 2

$60.79

Explanation:

First take off the 30% from $78.95. That will leave you with $55.265.

Add 6% of $78.95 for sales tax (4.737) to the $55,265 = $60.002

Then add the 1% of $78.95 for local option tax (.7895) to the $60.002.

That gives you $60.7915 - round it to the nearest cent and it gives you

$60.79
