Mrs. Murphy bought balloons, garlands, paper lanterns, and banners to decorate for a school party. She bought 3 times as many bags of balloons
as paper lanterns, 7 more garlands than paper lanterns, and 4 banners. She
paid $5.25 for each banner, $6.50 for each paper lantern, $5 for each bag
of balloons, and $3.50 for each garland. How many of each kind
of decoration did she purchase if she paid $145.50? please help

Banners: 4

Paper lanters: 3

Bags of Balloons: 6

Garlands: 11

Step-by-step explanation:

Banner: 4*5.25= $21

Paper lantern: 6.50*x=?

Balloons: 5*x=?

Garland: 3.50*x=?

Paper lantern: 145.50/6.50= $22.3

22.3/6.50= 3.4 round to 3

3 paper lanterns

Balloons: 145.50/5= $29.1

29.1/5= 5.8 round to 6

6 packs of balloons

Garland: 145.50/3.50= $41.5

41.5/10= 4.15

4.15+7=11.15 round to 11

11 garlands

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.
