Question

Rachel spent $\$24.15$ on vegetables. She bought $2$ lbs of onions, $3$ lbs of carrots and $1$ $\frac{1}{2}$ lbs of mushrooms. If the onions cost $\$3.69$ per lb, and the carrots cost $\$4.29$ per lb, what is the price per lb of mushrooms?

• A. $2.60
• B. $2.25
• C. $2.80
• D. $3.10
• E. $2.75

Answer 1

Answer: (A)

$2.60

We have $2\times 3.69+3\times 4.29+\frac{3}{2}\times x=24.15$ ($x$ is cost of mushrooms)
$\Rightarrow \frac{3x}{2}=24.15-20.25=3.9$
$\Rightarrow x=2.6$
