Question

Niyati is making a short-length necklace. Write an expression that shows how much it will cost Niyati for the chain, pendant, and b beads that cost $1 each. Then, find the total cost of the necklace if Niyati uses 25 beads.

Answer 1

The expression that shows the cost of the necklace is 1 + 1 + b*1, and if Niyati uses 25 beads, the total cost would be $27.

Step-by-step explanation:

To find the expression that shows how much it will cost Niyati for the chain, pendant, and b beads, we can use the formula: 1 + 1 + b*1. Since each bead costs $1, we can substitute the value of b with 25 to find the total cost. Therefore, the expression is: 1 + 1 + 25*1. Evaluating the expression, the total cost of the necklace would be $27.
