Question

siti paid a total of $98 for a necklace and a purse.The necklace cost $18.2 more than the purse.Find the cost of the necklace​

Answer 1

Answer: $58.10 is the cost of the necklace.

Step-by-step explanation:

let x=the cost of the purse

let x+18.2=the cost of the necklace

Set up an equation to solve for x:

x+(x+18.2)=98

Simplify:

2x+18.2=98

Subtract 18.2 from both sides:

(2x+18.2)-18.2=98-18.2

Simplify:

2x=79.8

Divide both sides by 2:

(2x)/2=79.8/2

Simplify:

x=39.9

Add 18.2 to x to solve for the cost of the necklace:

cost of necklace: x+18.2=39.9+18.2=58.1
