There was a box of stamps. Grace took 41 of the stamps and an additional 5 stamps. Melissa took 52 of the remainder and an additional 3 stamps. There were 84 stamps left in the box. How many stamps were in the box at first?
Q. There was a box of stamps. Grace took 41 of the stamps and an additional 5 stamps. Melissa took 52 of the remainder and an additional 3 stamps. There were 84 stamps left in the box. How many stamps were in the box at first?
Denote Stamps as S: Let's denote the total number of stamps at first as S. Grace took 41 of the stamps and an additional 5 stamps. So, the stamps taken by Grace can be represented as 41S+5.
Grace's Stamps Calculation: After Grace took her share, the remainder of the stamps is S−(41S+5). This simplifies to 43S−5.
Remaining Stamps After Grace: Melissa then took (52) of the remainder and an additional 3 stamps. The stamps taken by Melissa can be represented as (52)((43)S−5)+3.
Melissa's Stamps Calculation: After Melissa took her share, there were 84 stamps left. So, the equation representing the situation after Melissa took her share is:(43)S−5−[(52)((43)S−5)+3]=84.
Equation After Melissa: Let's simplify the equation step by step. First, distribute the (52) across the terms inside the brackets: (43)S−5−(52)(43)S+(52)(5)−3=84.
