Which expressions are equivalent to 2.5 – 4(1.5 – 10) + 3? Select all that apply. A 2.5+4(–1.5+10)+3
B 2.5–4+3(1.5–10)
C 2.5–4(10–1.5)+3
D 3+2.5–4(1.5–10) E –4(1.5–10)+3+2.5 F 4–2.5(1.5–10)+3

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.
