ron bought two wrist watches for his sisters that each cost x dollars. he also bought a pair of sunglasses for himself. the sunglasses cost $14 more than one wrist watch.
if he paid a total of $39.38 at the store, what is the cost of each wrist watch, in dollars?

Explanation:

Step1: Define variables & equation

Let $x$ = cost of 1 watch.
Total cost: $2x + (x + 14) = 39.38$

Step2: Simplify left side

Combine like terms:
$3x + 14 = 39.38$

Step3: Isolate $3x$

Subtract 14 from both sides:
$3x = 39.38 - 14 = 25.38$

Step4: Solve for $x$

Divide by 3:
$x = \frac{25.38}{3} = 8.46$

Answer:

8.46
