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

Eddi Din [679]

Yes, you are right. To solve for a variable means to put it on one side by itself, in terms of the other variables or values. To move something to the opposite side you do the opposite operation. Then you do the same thing to both sides of the equation.
