Marilyn, Sharon, and Rhonda collect earrings. Marilyn has half as many earrings as Sharon. Rhonda has 15 more earrings than Marilyn. Let x represent the number of earrings that Sharon has. Which algebraic expression represents the number of earrings Rhonda has?
A. x + 15
B.0.5x + 15
C.x − 15
D.15 − 0.5x
Sharon ---- x
Marilyn has half as many earrings as Sharon -----> Marilyn has x/2
Rhonda has 15 more earrings than Marilyn ----- Rhonda has x/2 + 15
x/2 + 15 is the same as .5x + 15 or (1/2)x + 15
To solve this problem, let's break down the given information:
1. Marilyn has half as many earrings as Sharon.
This can be written as: Marilyn = 0.5x, where x represents the number of earrings Sharon has.
2. Rhonda has 15 more earrings than Marilyn.
This can be written as: Rhonda = Marilyn + 15.
Since Marilyn = 0.5x, we substitute this in the equation: Rhonda = 0.5x + 15.
Therefore, the algebraic expression that represents the number of earrings Rhonda has is A. x + 15.
