• Use the EPSE model to solve the
following word problem:
Mrs. Nurre want to buy a Blue
Ray Player that costs \$460.
She plans to make a down
payment of \$100 and pay the
rest in eight equal payments.
What will be the amount of
each payment?

Plan
Need to find:
What will be the amount of
each payment?
(Facts Underlined in problem)
Costs \$460
Down payment of \$100
Pay rest in 8 equal payments
Solve
Strategy:
Subtract down payment from
the cost; then divide into equal
payments
Examine
Show work:
460 – 100 = 360
360 &divide; 8 = 45
\$45.
Did I answer the right question?
yes
Yes, because \$45 x 8 = \$360
and \$360 + \$100 = \$460 and
that’s how much the Blue Ray
Player cost.
