<h2>Answer: $6.96 - How to get the answer ↓</h2>
__________________________________________________________
Well first start to multiply by 7
7 x 1 = 7
7 x 2 = 14
7 x 3 = 21
7 x 4 = 28
7 x 5 = 35
Because '7 x 5' is greater than 29, We will use '7 x 4' which is 28
7 boxes = 1.68
From the '7 x 4' we then again multiply '4 x 1.68' which is 6.72
So now we know 28 boxes = $6.72
But were still missing one box.
Now we divide '1.68 ÷ 7' this equation equals to '0.24'
With this information we can assume that-
1 Box = 0.24¢
Now we add '6.72' + '0.24' to add one more box to the 28 boxes.
We get '$6.96'
So now we know that 29 boxes will cost <u><em>$6.96 </em></u>dollars.
