Answer:

1. Gerome have 261 post cards while Saul have 112 post cards.

2. John paid Php. 272.00 for four burgers.

Step-by-step explanation:

1. find the probability: 87 (Paul cards)

87 x 3 = 261 (Gerome cards)

87 + 25 = 112 (Saul cards)

261 + 112 + 87 = 460 (exact)

2. find the probability: 34 pesos (1 orange juice)

34 x 2 = 68 (like the problem said, the burger cost twice as much as the orange juice so the burger cost 68 pesos each)

68 x 4 = 272 pesos (4 burgers)

we have to multiply 34 x 2 again for the price of 2 juice

34 x 2 = 68 pesos (price of 2 juice)

272 + 68 = 340 pesos (exact)
