First, let’s multiply 34.4 to get 1% of that price.
34.4 x 0.01 = 0.344
Then, let’s multiply that 1% by 80 to get the price of the remote controlled boat, since it’s 4/5 the price of the helicopter.
0.344 x 80 = 27.52
$27.52 is the regular price of the boat.
Now, let’s find the 8% of that price. We’ll first first 1% and then multiply our answer by 8 to get 8%.
27.52 x 0.01 = 0.2752
0.2752 x 8 = 2.2016
Sales tax will be $2.20
The total will add the sales tax to the regular total of the boat.
$27.52 + $2.20 = $29.72
$29.72 is your answer.

Hope that helped! :)
