Susie wants to paint the outside of her dollhouse, but she will need to buy a special type of acrylic paint. If each bottle of acrylic paints covers 25
square feet, how many bottles of acrylic paint will be needed to paint the
dollhouse?

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

so, it becomes,

hence, first option 'a'   is correct.
