Answer:
about 180
Step-by-step explanation:
(when rounding, numbers 0-4 "stay" meaning you'd round down. If the numbers are 5-9, you round up)
91 rounded to the nearest ten would be 90
94 rounded to the nearest ten would be 90 as well
So, 90 + 90 = 180
Technically though, 91+94 = 185. So rounding this to the nearest ten would be 190.
Do what you will :)
