Mr. Martinez is comparing the price of oranges from several different markets. Which market’s pricing guide is based on a constant unit price? a, b,c or d

the answer is D

Step-by-step explanation: if you look at it the only answer that is changing by the same number consistently is the letter D. the rate is 3.00 for every 5 oranges

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
