Question

Fourteen percent of the town's population is over the age of 65. If there are 320 residents over the age of 65, approximately what is the town's population? (round to nearest whole number)A toy manufacturer estimates that 6% of its products are defective. If it produces 550 toys in one day, how many will be defective?

Answer 1

The town's population is approximately 44. The number of defective toys is approximately 33.

Step-by-step explanation:

To find the town's population, we can set up a proportion using the given information. Let x represent the town's population:

(320 residents over 65)/(x total residents) = (14% over 65)/(100% total population)

Solving for x, we can cross multiply and divide:

320x = 14x100

x = (14x100)/320

x ≈ 43.75

Rounding to the nearest whole number, the town's population is approximately 44.

To find the number of defective toys, multiply the total number of toys produced by the defective rate:

550 toys × 6% defective = 33 toys

Therefore, approximately 33 toys will be defective.
