Okay so you have to do 5 times 10 then you will have to do 8 time 8 times 40 so after you get your answer you would do the ratio 50 to 320 50:320

you must look to the ten-thousandths place, and if it is a 5 or higher, round up. if it is a four or less, round down.

The question is an illustration of selection (or combination)

The number of lock combination is 343

The given parameters are:

$n = 7$ --- the number of digits to select from

$r = 3$ --- the number of digits the lock uses

Because the digits can be repeated, the number of lock combinations is:

$Lock = n^r$

So, we have:

$Lock = 7^3$

$Lock = 343$

Hence, the number of lock combination is 343
