Answer:E. 4% decreaseStep-by-step explanation:To find out if we had an increase or a decrease, we will first need to set out variables.80 boys 95 girlsSo last year we had a total of:80 + 95 = 175 Track team membersThis year we had an increase in the number of boys.15% boys or 0.15Now since it's an increase, we add 1 to 0.15.Total number of boys = 80 x (1.15)Total number of boys = 92Then we had a decrease in the number of girls.20% girls or 0.20Now we take the number of girls and multiply them by 0.20 and subtract the amount we get to the number of girls initially.Total number of girls = 95 - (95 x 0.20) Total number of girls = 95 - 19 Total number of girls = 76So all together we have:92 boys + 76 girls = 168Now let's get the difference of the number of members last year and this year.175 - 168 = 7So we have 7 less members from last year.Now we find how many percent 7 members is of 175 members.Now we divide 7 by 175.7 / 175 = 0.04Then we multiply 0.04 by 100 to get the percentage value.0.04 x 100 = 4%So since we know that we have less than the initial number of members, then it means that it is a decrease.So we had a 4% decrease in the number of members.
