Randy buys a pair of shoes that were originally priced at $147. He receives a 35% discount and pays 8.5% sales tax. How much doe

maksim [4K]

Begin by subtracting 35% from 100%, giving 65% which is equivalent to 0.65
Then multiply
147 * 0.67 = 98.49
Now for a sales tax you would want to multiply by 108.5% (or 1.085) as you are paying the previous price and them some
98.49 * 1.085 = <span>106.86165
You can round to the second decimal place since you can't have a monetary value less than a penny
your answer would be $106.86

Unit value of 1rst one, 4.99/6 = 0.83

Unit value of 2nd one, 7.99/10 = 0.79

As, 2nd one is cheaper, so it is better :))

Mrac [35]

Answer:

The value of x will be 8

Step-by-step explanation:

We have given that $2\sqrt{x}=32$

We have to find the value of x

As $2\sqrt{x}=32$

For finding the value of x we have to square both side

On squaring both side

We done squaring both side for easy simplification

$4x=32$

So x = 8

So the value of x will be 8
