Question

The table shows the numbers of sets of twins, triplets, quadruplets, and quintuplets registered at a twin convention. Write and evaluate an expression for the total number of people who registered at the convention. Type Sets Twins 2697 Triplets 29 Quadruplets 2 Quintuplets 1

Answer 1

Total number of people registering at the convention = A

Twins = X = 2697
Triplets = Y = 29 
Quadruplets = Z = 2
Quintuplets = W = 1

The expression for Total A = 2 * X + 3 * Y + 4 * Z + 5 * W

evaluation:  A = 2 * 2697 + 3 * 29 + 4 * 2 + 5 * 1
                      = 5394 + 58 + 8 + 5
                      = 5, 465   =  total number of people
