at the school dance the ratio of students who bought snacks to the students who do not buy snacks is 426 based on this ratio how many of these students would buy a snack if there were a total of 180 students that attended the dance
Let the total number of customers that day be "x" 30% of total customers bought a snack and that is 120. So we can say: 30% of total (x) is 120 Note: 30% converted to decimal is 30/100 = 0.3 This can be translated to an algebraic equation as: 0.3x = 120 Now, we can solve for x, the total customers: 0.3x = 120 x = 120/0.3 x = 400 Since, 80% bought drink, we find 80% of 400: 80% = 80/100 = 0.8 0.8 * 400 = 320 The store sold 320 drinks and 120 snacks. So drinks outweigh snacks be: 320 - 120 = 200 So, 200 more drinks than snacks
