In c cents you can buy w widgets
1 dollar= 100 cents
1/100 dollar=1 cent
c*(1/100)=c cents
(c/100) dollar you can buy w widgets
In 1 dollar you can buy= w/(c/100)
So, in d dollars, you can buy= (100w/c)*d =100wd/c
Answer: A
1 dollar= 100 cents
1/100 dollar=1 cent
c*(1/100)=c cents
(c/100) dollar you can buy w widgets
In 1 dollar you can buy= w/(c/100)
So, in d dollars, you can buy= (100w/c)*d =100wd/c

If 2 widgets cost 10 cents, then widgets cost 5 cents each, and for 3 dollars, you can get 60. Which of the choices equals 60 when w = 2, c = 10, and d = 3? Only A.
\(\\
\frac{Widgets}{Cents}=\frac{w}{c}=\frac{x}{100d}\\
\\
x= \frac{100dw}{c}\)
