Can anyone solve this for me I don’t really understand it ?

answer is that you have to multiply 3% by the amount of the total price per house

Step-by-step explanation:

so first if you don't have a TI-30x then you have to turn 3% into decimal form which would be 0.03 now that we got that done next you have to multiply by the whole amount of every house so start with 0.03 x 510,000= which once you find out the total amount for that house would be $15,300 next is 0.03 x 625,000= $18,750 , now 0.03 x 780,000 = which is $23,400 and finally 0.03 x 650,000 = is $19,500 now to answer how much was made throughout the year take all the amount and add them up like this $15,300+$18,750+$23,400+$19,500= which ends up being $76,950 for the whole year before tax

Hopefully it helped you and please make me brainlist ?! would be very appreciated
