Answer:
C. Andrew can paint 7 houses in 28 days.
Step-by-step explanation:
Andrew can paint a house in 4 days, to check which statement is okay you just have to create an equation, the number of houses will be represented by "x" and the number of days it took will be Y you just check all the statements, for example:
Andrew can paint 9 houses in 27 days, x=9 y=27.
Y= 4x= 27= 4(9)
27= 36
As this is not correct, the statement is also in correct, the only statement that matches the math is the third one, Andrew can paint 7 houses in 28 days. X=7 Y=28
Y=7x
28=4(7)
28=28
As the math is correct the option that actually fits the equation would be the third one.
