Answer:
The ratio of flour to sugar is 2:1
Step-by-step explanation:
Let f = weight of a bag of flour
Let s = weight of a bag of sugar
3f+2s = 32
4f = 32
We have 2 equations and 2 unknowns, we can solve
4f=32
Divide by 4
4f/4 = 32/4
f = 8
Each bag of flour weights 8 pounds
Substitute this back into the first equation
3(8) +2s = 32
24+2s = 32
Subtract 24 from each side
24-24 +2s =32-24
2s = 8
Divide by 2
2s/2 = 8/2
s = 4 pounds
Flours weighs 8 pounds and sugar weights 4 pounds
We want the ratio of flour to sugar
Flour: sugar
8:4
We can divide each side by 4
8/4: 4/4
2:1

Unit rate refers to how much the buyer paid per unit. Let’s do the math:
$2.52 for 4.5 pounds of potatoes
Divide $2.52 by 4.5
The shopper paid 56 cents per pound of potatoes.
Now $7.75 spent for 2.5 pounds of broccoli.
Divide $7.75 by 2.5.
The shopper paid $3.10 for each pound of broccoli.
Last $2.45 for 2.5 pounds of pears.
The shopper will spend 98 cents per pounds of pears.
