Question

Luke can buy bottles of water in packages of 6 for $15.24 or in packages of 4 for $11.16. How much money does he save by buying 48 bottles of water at the better price?

Answer 1

Answer:

$6\ for\ \ 15.24\ is\ better\ price\\\\Total\ saving=\ 12$

Step-by-step explanation:

Cost at the rate 6 for $15.24:

Cost of $6$ bottles$=\ 15.24$

Cost of $1$ bottle$=\ \frac{15.24}{6}$

Cost of $48$ bottles$=\frac{15.24}{6}\times 48=15.24\times 8=\ 121.92$

Cost at the rate 4 for $11.16:

Cost of $4$ bottles$=\ 11.16$

Cost of $1$ bottle$=\frac{11.16}{4}$

Cost of $48$ bottles$=\frac{11.16}{4}\times 48=11.16\times 12=\ 133.92$

Hence $6\ bottles\ for\ 15.24$ is less expensive.

Total saving$=133.92-121.92=\ 12$
