Super stuck.. Really quick one probably

Really stuck on this question.

3 ( 5 + 3 ( 10 + 4.8 ))

I figure it's 148.2, but the multiple choice options are

393
1,008
1,023

Can anyone help with this?

Thanks in advance.

I got 148.2 as well, are you sure you transcribed the problem correctly?

Math Focus: Yet to find out.
I rearranged the numbers a bunch of times and couldn't get any of the answers either .

It's probably intended to be 3(5 + 3 (10 + 4·8)), where the dot denotes multiplication, which has value 393.

Yes, I think you're right. The dot is in the middle; I wasn't aware that meant multiply. I asked this on behalf of an American friend (I'm from the UK). I noticed the decimal point was oddly placed, but I thought Americans displayed differently or something... Kind of stupid now that I think about it.

Well I guess that's settled then. Thanks a lot!

The raised dot used to be the conventional decimal separator in the UK, with an unraised dot being used at the end of a sentence and for multiplication. The standard was changed quite some time ago (possibly in the 1980s), probably due to pressure from mainland Europe, and because the raised dot wasn't available on most computer keyboards. Similar pressure to replace the "," in, say, "1,000" with a space ("1 000") was less successful.
