Sadie is drawing a scale drawing of her room, which is 9 ft. by 10 ft. Which scale could she use if she wants to fit her drawing on a piece of paper measuring 8.5 in. by 11 in.?

A) 1 inch = 1 foot
B) 1.5 inch = 1 foot
C) 0.75 = 1 foot
D) 2 inches = 1 foot

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

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

yes.. it's proven to be 36.
