Lilly has $35,she went to the store and spender 10% of it,how much money she has left?

kirill115 [55]

Hi there! Lily has $31.50 left.

To find our answer we first need to know the amount of money Lily spend.
$10\% \times 35 = 0.1 \times 35 = 3.50$

Therefore, Lily spend $3.50. Now we subtract this amount of money from the amount she initially owned.

$35 - 3.50 = 31.50$
Hence, Lily has $31.50 left.
