Ken is building an outdoor walking path
Pavers are sold 10 for $8 or $1 per paver
Ken needs 52 pavers to complete the walking path
if 10 pavers is sold for $8
52 / 10 = 5 remainder 2
This means he is going to buy 50 pavers for
5 x $8 = $40
Remaining two pavers
Since, 1 paver is sold for $1
The 2 pavers will be sold for $2
$40 + $2 = $42
The least amount that 52 pavers will cost is $42
