Answer:

x > 22

Step-by-step explanation:

Deena has already taken 126 calls

She takes 7 calls per hour ( think slope)

y = mx+b

y = 7x+126

She needs to take at least 280 calls. So what she does must be greater than 280

280 <7x+126

We need to isolate x. The first step is to subtract 126 from each side

280-126 < 7x + 126 -126

154 < 7x

Next, we divide by 7 on each side

154/7 < 7x/7

22 < x

azamat

Answer:

1250000

Step-by-step explanation:

Let number of the total number of shoes sold be 'y'

y*(70/100)= 875000

70y = 875000*100

y = (875000*100)/70

y = 1250000

Given the original number n. Multiply the number by 9. Add 99. Divide this sum by 9. Subtract the original number, n, from the q

tangare [24]

Answer:

Step-by-step explanation:

Hello,

Given the original number n.

$\large \boxed{n}$

Multiply the number by 9.

$\large \boxed{9n}$

Add 99.

$\large \boxed{9n+99}$

Divide this sum by 9.

$\large \boxed{\dfrac{9n+99}{9}=n+11}$

Subtract the original number, n, from the quotient.

$\large \boxed{n+11-n=11}$

Thank you.

a retailer buys a radio from the wholesaler for $75.he then marks up the price by 1/3 and sells it at a discount of 20%.what was

soldier1979 [14.2K]

He makes it up by 1/3=.333%=$75*1.333=$99.98
he then discounts it by 20%=1/5=99.98/5=$19.99
If the original profit is $99.98-$75=$24.98
and then discounted by $19.99
it would be $24.98-$19.99
=
$4.99
