Question

d = number of dollars
p = number of pounds
drag each table and equation to the unit rate it matches.
(first table: d and p columns, rows (1, 1/9), (9, 1), (18, 2); second table: d and p columns, rows (3, 1), (6, 2), (12, 4); equation: p = 3d)
unit rate = 3 dollars/pound
unit rate = 1/3 dollars/pound
unit rate = 9 dollars/pound

Explanation:

Step1: Calculate rate for first table

For the first table, use $\frac{d}{p}$. For $d=9, p=1$: $\frac{9}{1}=9$ dollars/pound.

Step2: Calculate rate for second table

For the second table, use $\frac{d}{p}$. For $d=3, p=1$: $\frac{3}{1}=3$ dollars/pound.

Step3: Rearrange equation for rate

From $p=3d$, solve for $\frac{d}{p}$: $\frac{d}{p}=\frac{1}{3}$ dollars/pound.

Answer:

• Unit Rate = 3 dollars/pound: Second table (d: 3,6,12; p:1,2,4)
• Unit Rate = $\frac{1}{3}$ dollars/pound: Equation $p=3d$
• Unit Rate = 9 dollars/pound: First table (d:1,9,18; p:$\frac{1}{9}$,1,2)
