9. Gloria bought each of her three younger siblings a movie ticket.
Find the total cost of the movie tickets if each ticket cost $9.75.
Justify your answer by using the Distributive Property.

14. Marty bought a shirt for $9.50, sandals for $15.50, shorts for $11.75,
and sunscreen for $5.25. Use mental math to find the total amount
he spent. Explain.
$42; Sample
answer: $9.50 +
$15.50 = $25
and $11.75 +
$5.25 = $17, $25
14. + $17 = $42.
15. Explain why the expression 7x + 5 cannot be factored.
The GCF of 7
and 5 is 1. If
the GCF of the
two terms is 1,
the expression
cannot be
15. factored.
