Question

Yuvi need some supplies for his business. He order items according to the following table.

Supply	Total number Needed	Cost Each
Textbook	$1$	24.99$
Notebooks	$5$	3.78$
Pencils	$20$	0.55$

If textbook makes up $n$ percent of Yuvi's total budget, then what is the value of $2n$?

Answer 1

Yuvi's total budget is $24.99+(5\times 3.78)+(20\times 0.55)=54.89$.

Hence the percentage of yuvi's budget that the text book takes is $=\frac{24.99}{54.89}=0.455$

Hence, $n=45.5$ %

Therefore, $2n=91$ %
