A study showed that 7/10 of the human body weight is water. If a person weighs 140 pounds, how many pounds is water?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Okay, so first let's note down the points we've in the question.

Fraction of body weight that's water = 7/10
Weight of the person = 140 pounds.
Number of pounds that's water = ?

To find how many pounds of the person who weighs 140 pounds is water, we need to multiply 140 into 7/10.

⇨ Let's solve it now.

$\sf \: 140 \times \frac{7}{10} \\ \sf = 14 \bcancel{0} \times \frac{7}{1 \bcancel{0}} \\ \sf = 14 \times 7 \\ = \boxed{\boxed{\bf \: 98 \: pounds}}$

A person who weighs 140 pounds will be approximately 98 pounds water.

A tire dealer sells 2 tires for as much as he paid for 3 tires. he paid $240 for a dozen tires. What is the total profit on 12 t

tester [92]

First, find how much he paid by tire.
To do so, divide what he paid by how many tires he bought like this :
240$ / 12 = 20$ per tire

Then, calculate how much he sells each tire.
To do so, start by calculating how much he paid for 3 tires:
20$ x 3 = 60$

This is the price he sells 2 tires for, therefore :
60$ / 2 = 30$
he sells his tires 30$ each.

Finally, you have to calculate the profit he made by selling 12.
We already know how much it cost, so you need to find how much money he gets selling them :
12 tires x 30$ = 360$

To find the profit, take off the amount he paid from the amount he made :
360$ - 240$ = 120$

There you go!
