2 Helpful Shopping Exercise
Exercise 2
Lisa has 4 quarters, 3 dimes, and 2 nickels. She wants to buy a toy that costs $1.45. Does she have enough money? Helpful guide shows how to check!
Helpful Definition:

Shopping helper: Step-by-step method to determine if you have enough money to buy something.

Lisa's Money
4 quarters + 3 dimes + 2 nickels
Toy Cost
$1.45
Lisa's Total
$1.50

$1.40 < $1.45, so Lisa does NOT have enough money

Lisa needs $0.05 more
Helpful Answer:

No, Lisa does not have enough money. She has $1.40 but needs $1.45. She is $0.05 short.
