Betty got $180

If its 2:3 and 2 is 120, that means 120/2 equals 60. 60*3=180
In order to find the total number of roses, we can use multiplication. Since there are 6 roses on each bush, we can say that the answer is: 6+6+6+6+6+6+6+6+6+6. Since multiplication is a way to quickly add the same number, we can use 6*10. This becomes 60.
Good luck :D
