A she She knows tha
. Donna orders boxes of batteries for calculators in the math
the number of batteries she gets, n, is proportional on how many boxes, b, of batteries s
buys. In previous years she has recorded the following:
11
15 21
number of boxes, b
44 60
84
number of batteries, n
What is the ratio of the number of batteries to the number of boxes? What does it represent?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
