Answer: $72

Step-by-step explanation:

90x.2=18

90-18=72

Hope this helped :)you turn your percent into a decimal and multiply it buy your original price and you get how much money you're saving which is 18 dollars then you subtract it by your original price

Answer:

Step-by-step explanation:

when asked to decrease a number by a certain percentage, take the original number as 100%

here 90 is equivalent to 100%.

We subtract 20% from 100% to get 80% ( that's the new value)

nataly862011 [7]

Step-by-step explanation:

write a formula that models this.

9.30x = money earned

If he works 2 hours, he'll get $9.30 times (2)

and so on. so you write and solve

9.30(1), 9.30(5), 9.30(8)

for the second part you want to substitute 180 for the amount earned which will become

9.30x = 180 then you solve for x

What is the range of function gif g(x) = -2/(x) + 1

Zina [86]

The function g(x) is a rational function, and none of the options represent the range of the function g(x)

<h3>How to determine the range of the function?</h3>

The function is given as:

g(x) = -2/x + 1

The above function is undefined at point x = 0.

This is so because -2/x is undefined.

So, we have:

g(0) = -undefined + 1

g(0) = undefined

This means that the range of the function is:

(-infinity, 1) and (1, infinity)

None of the options represent the range of the function g(x)
