Olivia are two times as much salad as Reagan. If Reagan ate R salad, which equation can be used to find the amount of salad Olivia are, v?

Explanation:

r = amount of salad Reagan ate

v = amount of salad Olivia ate

"Olivia ate twice as much as Reagan", meaning

amount Olivia ate = 2*(amount Reagan ate)

v = 2*r

v = 2r

2r = v
