If Andrew can paint 1 house in 4 days, which sentence is true? A. Andrew can paint 9 houses in 27 days. B. Andrew can paint 8 houses in 30 days. C. Andrew can paint 7 houses in 28 days. D. Andrew can paint 6 houses in 18 days.

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.

The answer is C.

Step-by-step explanation:

I got this by multiplying the houses by the days it would take to paint to paint one house.

9*4=27
