Question

Tony's cat weighs c pounds. Three months from know, the cat's weight is expected to increase by 12.5% Write two expressions to represent the cat's weight in three months.

Answer 1

Explanation:

Tony's cat weighs c pounds. This means that the cat currently weighs c pounds.

Three months from know, the cat's weight is expected to increase by 12.5%. This means that in three months time, the weight of the cat is expected to be the sum of its current rate × 12.5 % of its current rate. It becomes

c + 12.5/100 × c = c + 0.125c

= 1.125c

So the two expressions that represent the cat's weight in three months would be

1) three months from now, the cat's weight will increase by 0.125c

2) three months from now, the new weight of the cat will be 1.125c
