(3 + 3 + 3) = 9 kitty toys ==> x + x + x = \$3x

Or,

3 × 3 = 9 kitty toys ==> 3 × x = \$3x

Sarin’s mother to pay \$3x for 9 Hello Kitty toys

3 kitty toys cost \$x

The cost of each kitty toys = x ÷ 3 = \$ x/3

Sarin’s mother to buy 9 kitty toys

The amount that Sarin.s mother need to pay = 9 ÷ x/3 = \$3x
