Bella is buying balloons for a back to school celebration. She sees there are 4 packages of 15 balloons for $18 and 5 packages of 10 balloons for $16. Which is
a better deal? How do you know? Are you comfortable with Bella's buying
habits? Why or why not? help plsss

The first unit price ($0.30/balloon) beats the second ($0.32/balloon).

Step-by-step explanation:

4 packages of 15 balloons for $18 works out to 1 package of 15 balloons for $18/4, or $4.50.  That'd be

$4.50

= $0.30/balloon.

15 balloons

Next:  5 packages of 10 for $16 works out to 1 package of 10 for $16/5, or

1 package of 10 for $3.20.  That'd be

  $3.20

= $0.32/balloon

10 balloons

The first unit price ($0.30/balloon) beats the second ($0.32/balloon).

If Bella understands the math involved in finding unit costs and actually does the work prior to buying anything, then I'm comfortable with her buying habits.
