Step-by-step explanation:
Vacuum dealer sold units in 2011 = 420
Vacuum dealer sold units in 2012 = 467

To solve this problem, we can make a proportion.
Since Kiara's money has a ratio of 9:7 in comparison to Tyler's, we can make the proportion as follows:
9/7=126/x, where x is Tyler's money. This can be simplified to 9=882/x, or 9x=882. Then, divide by 9 to find x, which results in x=98.
Now we know that Tyler has $98, so we just need to add 126 to 98 and get $224 all together.
Hope this helps!
