When a snowstorm hit the town of Clarkesville, there already were 4 inches of snow on the ground. The storm lasted for 2 hours,
Olin [163]

Answer:

Rate of snow fall per hour ≥ 1 inches per hour

Step-by-step explanation:

Given:

Amount of snow already settled = 4 inches

Time period of snow fall = 2 hour

New amount of snow = least 6 inches

Computation:

Extra amount of snow ≥ New amount of snow - Amount of snow already settled

Extra amount of snow ≥ 6 - 4

Extra amount of snow ≥ 2 inches

Rate of snow fall per hour ≥ Extra amount of snow / Time period of snow fall

Rate of snow fall per hour ≥ 2 / 2

Rate of snow fall per hour ≥ 1 inches per hour

a pair of jeans originally cost $140 and are now on sale for 65% off. what is the sale price of the jeans
Andrei [34K]

Answer:

$49

Step-by-step explanation:

<u><em>Method 1</em></u><u><em>:</em></u>

100% - 65% = 35%

\frac{y}{140}: \frac{35}{100}

y · 100 = 35 · 140

100y = 4900

100y ÷ 100 = 4900 ÷ 100

y = 49

<u><em>Method 2</em></u><u><em>:</em></u>

\frac{y}{140}: \frac{65}{100}

y · 100 = 65 · 140

100y = 9100

100y ÷ 100 = 9100 ÷ 100

y = 91

$140 - $91 = $49

A store has clearance items that have been marked down by 35%. They are having a sale, advertising an additional 45% off clearan
wariber [46]
Your answer is 35.75%.

Let’s pretend something at the store is $100. (It will save some math later)

100 - 35% leaves 65% (0.65 as a decimal)
100 x 0.65 = 65
That’s the price after the first discount. If we take 45% off of the sale price, we’ll be left with 55%, 0.55

65 x 0.55 = $35.75

Now normally you’d compare 35.75(sale price)/ 100(original price) to % off (x)/100, but doe this example, it’s unnecessary.

35.75/100 = x%/100
