Q. Linda is selling handmade jewelry to earn money for camp. Bracelets sell for

\$3

and necklaces sell for

\$15

, and she needs to make at least

\$320

in revenue to cover the cost of camp.

\newline

Select the inequality in standard form that describes this situation. Use the given numbers and the following variables.

\newline

x =

the number of bracelets

\newline

y =

the number of necklaces

\newline

Choices:

\newline

(A)

3x + 15y \leq 320

\newline

(B)

3x + 15y > 320

\newline

(C)

3x + 15y \geq 320

\newline

(D)

3x + 15y < 320

Calculate Bracelets Revenue: Bracelets cost $\$3$ each, so if $x$ is the number of bracelets sold, then the total revenue from bracelets is $3x$ .
Calculate Necklaces Revenue: Necklaces cost $\$15$ each, so if $y$ is the number of necklaces sold, then the total revenue from necklaces is $15y$ .
Determine Minimum Revenue: Linda needs to make at least $\$320$ , so the combined revenue from bracelets and necklaces should be greater than or equal to $\$320$ .
Formulate Inequality: The inequality that represents this situation is $3x + 15y \geq 320$ .
