The formula for unit rate is blank over blank = x over one. She types 496 words in 8 minutes, otherwise said "496 words per 8 minutes", which means its 496 over 8. If you do cross multiplication, 496*1 = 496 (Obviously) and 8*x = 8x.

Now, you have 496 = 8x. To isolate the variable, do the opposite of what it says 8x divided by 8 = x. Of course, you have to do the same thing on both sides. 496 divided by 8 is 62. so the unit rate is 62 words per minute.

At Greenwood Landscaping, rock costs $47.50 per ton. How much would 2.5 tons cost?
Grace [21]

Answer:

Hey!

Your answer is $118.75!

Step-by-step explanation: How did I get this?

<u>STEP 1:</u> So we know that for a ton of rock costs us $47.50...

To get 2 tons all we have to do is to MULTIPLY $47.50 by 2...

<em><u>(47.50 x 2 = 95)</u></em>

<u>STEP 2: </u>So for $95, you will get 2 tons of rock!

Now to get the .5 tons of rock in price form, we have to get the price of the whole 2.5 tons and DIVIDE BY 2

<em><u>(47.50 ÷ 2 = 23.75)</u></em>

<u>STEP 3:</u> So now we have the costs for 2 tons and the price for HALF a ton.

What we do now is easy...we ADD THE VALUES TOGTHER!

<em><u>(95 + 23.75 = $118.75)</u></em>

The result of $118.75 after adding them together is the PRICE OF 2 TONS!

<u>I HOPE THIS HELPED YOU!</u>
