Question

Cost of a apple juice is $\$0.30$ per $500\text{mL}.$ The vendor charges an additional $5¢$ per serving. Generate a rate chart for the juice.

• A. Quantity (mL) Rate (¢)

  $100$	$6$
  $250$	$15$
  $400$	$24$
  $500$	$30$
  $750$	$45$

• B. Quantity (mL) Rate (¢)

  $100$	$11$
  $250$	$20$
  $400$	$29$
  $500$	$35$
  $750$	$50$

Answer 1

The correct option is B Quantity (mL) Rate (¢)

$100$	$11$
$250$	$20$
$400$	$29$
$500$	$35$
$750$	$50$

$500\text{mL}$ of the juice cost $\$0.30=30¢$

$\to 100\text{mL}$ of the juice will cost $\frac{30}{5}=6¢$
Cost of $100\text{mL}$ of the juice with serving charges $=6+5=11¢$

$\to 250\text{mL}$ of the juice will cost $6\times 2.5=15¢$
Cost of $250\text{mL}$ of the juice with serving charges $=15+5=20¢$

Similarly, other rates are generated to form the rate chart.
Quantity (mL) Rate (¢)

$100$	$11$
$250$	$20$
$400$	$29$
$500$	$35$
$750$	$50$
