The answer is 119.5. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
It is: 100+250 = 350
250 + 100 = 350
100 + 100 + 50 = 250
150 + 100 = 250
It is: 120/100*250 = 300
600 + 250 = 850
26,600,000
325
351
200 + 300 200 + 200 + 100
100 has one, 150 has 2, 250 has 2.
It is: (250/100)*100 = 250%
