Tom and Jerry each has some money. if Tom spends $90/day and Jerry
Maru [420]

Answer:

$400

Step-by-step explanation:

Let T be Tom's initial money amount and J be Jerry's initial money amount.

T - \$90*n_1 = \$1100\\J - \$45*n_1 = 0\\\\T - \$45*n_2 = \$1700\\J - \$90*n_2 = 0\\

Solving this linear system:

T-2J =\$1100\\2T-J = \$3400\\3J=\$3,400-\$2,200\\J=\$400

Jerry initially had $400.
