Question

Tamara is makingamedium-length necklace.Write an expression that shows how much it will cost Tamara forthe chain, pendant, andbbeads that cost $0.25 each. Then findthe total cost of the necklace if Tamara uses 30 beads.

Answer 1

The total cost of the necklace will be $8.

Let's denote the cost of the chain, pendant, and beads by the variable

C. Since each chain, pendant, and bead costs $0.25, the expression for the total cost (T) of the necklace can be expressed as:

T=C+C+30×0.25

Simplifying this expression:

T=2C+7.5

Now, if Tamara uses 30 beads, we can substitute

C with $0.25 in the expression:

T=2×0.25+7.5

T=0.5+7.5

T=8

So, the total cost of the necklace will be $8.
