Frank created the following table to figure out a mixture problem.

	Total cost ($)		Price ($/pound)		Amount of candy (pounds)
Jellybeans	$\displaystyle{0.5}{\left({p}+{3}\right)}\usepackage{cmbright}\Huge\$	=	$\displaystyle{p}+{3}\usepackage{cmbright}\Huge\$	*	0.5
Gumdrops	$\displaystyle{1.5}{p}\usepackage{cmbright}\Huge\$	=	$\displaystyle{p}\usepackage{cmbright}\Huge\$	*	1.5
"Beanbag"	10.00	=		*	2

If the table is a correct representation of the problem, which of the following problems was he solving?
