The discounted amount of pair of pants is $37.4
<u>Solution:</u>
Given, A pair of pants regularly costs $68.
The pants are on sale for 45% of the original price.
We have to find that how much will the discount be?
Now, <em>discounted amount = original price – sold price
</em>
Discounted amount = original price – 45% of original price
Discounted amount = $68 – 45% of $68
![\begin{array}{l}{=68-\frac{45}{100} \times 68=68\left(1-\frac{45}{100}\right)=68 \times \frac{100-45}{100}=68 \times \frac{55}{100}} \\\\ {=\frac{3740}{100}=\$ 37.4}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%3D68-%5Cfrac%7B45%7D%7B100%7D%20%5Ctimes%2068%3D68%5Cleft%281-%5Cfrac%7B45%7D%7B100%7D%5Cright%29%3D68%20%5Ctimes%20%5Cfrac%7B100-45%7D%7B100%7D%3D68%20%5Ctimes%20%5Cfrac%7B55%7D%7B100%7D%7D%20%5C%5C%5C%5C%20%7B%3D%5Cfrac%7B3740%7D%7B100%7D%3D%5C%24%2037.4%7D%5Cend%7Barray%7D)
Hence, the discounted amount is $37.4
Answer:
h = 12.5
Step-by-step explanation:
Simplifying
h + 3h + 4h = 100
Combine like terms: h + 3h = 4h
4h + 4h = 100
Combine like terms: 4h + 4h = 8h
8h = 100
Solving
8h = 100
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by '8'.
h = 12.5
Simplifying
h = 12.5
