(a) The number of people who registered to vote in the last year is 60. By using the  percentage change  in the number of registers from this year to the last year, the required value is evaluated.  (b) We need to pay $78 for a wrestling suit with a total  discount  of 35%.    How to calculate the percentage change?  The percentage change formula is  % change = 100 × (new value - old value)/old value  How to calculate the price after the discount?   The  discount percentage  is converted to decimal  Then, multiply the original price by the discount (decimal)  The obtained value is the money we save. So, subtracting it from the original price, we get the price after the discount.  That is nothing but the selling price     Calculation:   (a)    It is given that,  This year, the number of registered people to vote is 66  This year 10% more people registered for voting than the last year.  Consider the number of people who registered in the last year = x  Then, the  percentage change  is  10 = 100 × (66 - x)/x  ⇒ 1/10 = (66 - x)/x  ⇒ x = 660 - 10x  ⇒ x + 10x = 660  ⇒ 11x =660  ∴ x = 660/11 = 60  Thus, the number of people who registered for voting in the last year is 60 people.   (b)   It is given that,   A sports store gives 20% off all items and an additional discount of 15% on all wrestling suits.  So, the  total discount  for the wrestling suit which costs $120 is   20% + 15% = 35%  Then, the total discount in decimal number = 35/100 = 0.35  Then, the  selling price  is  = original price - original price × 0.35   = 120 - 120 × 0.35  = 120 - 42  = $78  Thus, we need to pay $78 for a wrestling suit in that store.
