Question

if Maria collected R rocks and Javy collected twice as many rocks as Maria and Pablo collected 5 less than Javy. What is the difference between rocks collected by Pablo and Maria?

Answer 1

Step 1: Let's review the information given to us to answer the exercise correctly

Number of rocks collected by Maria = R

Number of rocks collected by Javy = 2R (Twice as many rocks as Maria)

Number of rocks collected by Pablo = 2R - 5 (Pablo collected 5 less than Javy)

Step 2: Let's find the difference betwen Pablo and Maria, this way:

Pablo - Maria

2R - 5 - R

R - 5

Step 3: The difference between rocks collected by Pablo and Maria is R - 5
