mr. pope is making cookies. for every 3 cups of flour that he uses, he uses 2 cups of sugar. how many cups of sugar does mr. pope need for one cup of flour?
a) 6 cups
b) $1\frac{1}{2}$ cups
c) $\frac{2}{3}$ cups
d) 1 cup

Explanation:

Step1: Find strips per candy bar

$\frac{12}{3}=4$

Step2: Match to equation

$s=4c$
---

Step1: Define cost relationship

Cost = Price × Pounds, so $c=2t$
---

Step1: Find cost per package

$\frac{5}{6}\approx0.83$

Step2: Match to equation

$c=0.83p$
---

Step1: Find sugar per flour cup

$\frac{2}{3}$

Step2: Match to option

$\frac{2}{3}$ cups

Answer:

1. (c) $s = 4c$
2. (a) $c = 2t$
3. (b) $c = 0.83p$
4. (c) $\frac{2}{3}$ cups
