1. Mr. Lazaro's class of 35 students is 3 times more than twice the number of
students in Mr. Gabuyo's class . How many students are there in Mr. Gabuyo's class ?
.
Question as posted:
L=number in Lazaro's class; G=number in Gabuyo's class
L=3(2(G))
35=6G
5.83=G
In the problem as posted, Mr. Gabuyo's class has 5.83 students.
.
If we change the problem slightly (3 more instead of 3 times more), it makes more sense:
1. Mr. Lazaro's class of 35 students is 3 more than twice the number of students in Mr. Gabuyo's class . How many students are there in Mr. Gabuyo's class ?
L=2G+3
35=2G+3
32=2G
16=G
In this case, all the students are whole.
Mr. Gabuyo's class has 16 whole students.
.
2. The 950 pesos cost of a pair of lady's shoes in marikina shoe store is only 100 pesos less than three times what is costs in icyland department store. How much is the cost of a pair of lady's shoes in icyland department store ?
.
I=cost in icyland
950 pesos+100 pesos=3I
1050 pesos=3I
350 pesos=I
ANSWER: The shoes cost 350 pesos in icyland department store.
