B: The number of people who RSVP decreases by 1 each day.
C: After the first day, 3 people have RSVP’ed to the invitation.
D: The number of people who RSVP increases by 2 people each day.

the answer is D

if you replace x by 1 the answer is 3

if you replace x by 2 the answer is 5

if you replace x by 3 the answer is 7

etc...

D

Step-by-step explanation:

given that no of days=x

let no of people=n

n=2(x-1)+3

at x=1, n=3

at x=2, n=5

at x=3, n=7

this shows an increase of 2 for every increase in the number of days

42

step-by-step explanation:

256/6=42

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
