Answer:
120.3
Step-by-step explanation:
51 + 69.3 = 120.3
Since 30% is the same as 0.30, multiply 0.30 by 720 to get 216. Answer is $216. Another way would be knowing that 30% is the same as the two of 30/100 or 3/10. This by multiplying 720 by 3 to get 2160 and then dividing by 10, you'd get the same answer. $216.
