Because you can only add and subtract radicals with the same radicand,
you get 2

that is the simplified answer but if you want it in decimals, 2.022 is what you get.
Answer:
$5.40
Step-by-step explanation:
First, figure out the cost of the items with tax; for Tommy we have 20*0.08 = 1.6, add that 1.6 to the 20 and his purchase is $21.6, for John we have 25*0.08 = 2, add 2 to his 25 and his purchase is $27. To find the difference we subtract 27-21.6 = 5.4 or $5.40
3*4*4=48
