Answer 1

Explanation:

I don't know!

Answer 2

2a + 20b +2xc = 2(a+10b+xc)

Explanation:

Let a = one litter box, b = one cat toy and c = a bag of cat food

The 1 litter box = a, 10 cat toys = 10b and x bags of cat food = xc

For one sister, purchase = a + 10b + xc

And for two sisters,

total purchase = 2 x ( a + 10b + xc ) = 2(a+10b+xc)

= 2a + 20b + 2xc
