Barry's deck of cards contains 40 blue cards and 70 red cards. Max's deck of cards contains the same number of blue cards, but the ratio of blue cards to red cards is 8:9. How many total cards does Max's deck of cards contain?

40:blue = 8:9
blue = 45
110
had this on my test, answer is 95
wait no it's the same guy who posted on January 29, 2017 the answer is 85

also ik im late
85, sorry if someone else already said it...
Oh sorry Anonymous, I also just did the test and I am correcting it Rn.
its 85 because if there are 40 b and 70 r and the 8;9 then 8 x 5 =40 so 9 x 5=45 and 40 + 45 = 85
85 is the answer
