Answer: 190
Step-by-step explanation:
We know to combine like terms, so ones like 50+20 make 70. We can then add up 35+15 and get 50. This gives us the equation of 70+70+50. We can add 70+70 and get 140. We then add 140+50, which gives 190.
50 + 20 = 70
70 + 35 = 105
105 + 70 = 175
175 + 15 = 190
so the answer is 190
70 + 35 = 105
105 + 70 = 175
175 + 15 = 190
so the answer is 190
