This luggage scale can measure weight to the nearest

Step-by-step explanation:

That luggage scale can measure weight to the nearest tenth.

If you observe, the scale is giving a number with only tenth in its decimal part, that's why we say that it measures to the nearest tenth.

If the scale shows 4.42, then we would say that the scale measures weight to the nearest hundredth, but that's not the case here.

Simply do 4000×0.08

Then take that amount say x and then multiply it by 2 and add it to 4000.

Same process for the second half
