What is 380 when it is increased by 18%

Yuri [45]

18%=0.18
380×0.18=68.4 increase
380+68.4=448.4

the easier way is to think 1 times any number is the same number so 380(1+0.18)=448.4 (just like adding tax to the price of something to see how much you'll actually pay)

A coffee pot holds 2quarts of coffee. How much is this in cups

Kobotan [32]

Answer:

8 cups

Step-by-step explanation:

1 quart = 4 cups

2 quarts = x cups

x = # of cups

$\large \textsf{$\dfrac{1}{2}$} = \large \textsf{$\dfrac{4}{x}$} \implies \normalsize \textsf{cross multiply}\\\\\large \textsf {$x$ = 8}$

Therefore, there are 8 cups in 2 quarts.

Hope this helps!
