shusha [124]

Answer:

see explanation

Step-by-step explanation:

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
creativ13 [48]

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

2. What is a benefit of the rule of law?
Firdavs [7]

I claim that this the correct answer is D.

The evidence that I recognize is the document named "The Magna Carta" written in 1215

The reason why this evidence supports my answer is because it required King John to protect the nobles' privileges and some rights. It also establishes the 'writ of habeas corpus'.
