Lenora and Rosaria are catching fireflies. Lenora has 136 fireflies in her jar. Rosaria had 152 fireflies, but then she caught 29 more. How many more fireflies does Rosaria have than Lenora?
Choose the equation that best represents this problem. (The letter f tells how many more fireflies Rosaria has than Lenora.)
136 + 152 + 29 = f
(152 + 29) - 136 = f
(136 + 29) -152 = f
152 - 136 - 29 = f
(152 + 29) - 136 = f
