Amanda, Maybelline and Owen participated in a charity drive by selling cookies. Amanda sold
\( {1 \over 3}\)of the total number of jars of cookies sold. Maybelline and Owen sold the remaining jars of cookies in the ratio 3:7. Owen sold 32 more jars of cookies than Amanda. If each jar was sold for $12, what was the total amount collected by the 3 children?
Let Amanda sold x cookies
1/3th is x cookies
the whole is 3x cookies
=> Maybelline sold = 3/10 x 2x = 8x/10 = 3x/5
Owen sold = 7/10 x 2x = 7x/5
given Owen sold 32 more jars than Amanda
=> 7x/5 = 32 + x
=> 2x/5 = 32 => x = 80
Total number of cookies = 3x
= 3(80)
= 240.
Total amount collected = 240 x 12
= $2880
