| the question asked for how many kids took ONLY italian. it said the number of students who took both subjects is equal to the number of students who took one subject. so that means 15 ppl took only one subject, either Italian or German...so since there were 3 more ppl who took german than italian, the number of people who took only german is 9, and the number of ppl who took only italian is 6. 9 + 6 =15 |
