Anna earns 50 points every time she shops at a grocery store. She needs a total of 3,470 points to receive a free prize. So far she has earned 320 points. How many more times will Anna have to shop at the grocery store in order to received a free prize?
I think its 63 times because 50X60 will get you 3,000 and you already have 320 so 3,000+320 is 3,320 and when you add 50, 3 more times you get 3,470 so it would be 63 times
