The pounds of pepper and the amount are illustrations of unit rates
She bought a total of 3 pounds of bell pepper
The amount spent is given as:
Red bell pepper = $2.90
Green bell pepper = $1.90
The price per pound for both type of pepper is given as:
Rate = $1.60 per pound
So, the total pound is calculated as:
Pound = Total amount / Rate
This gives
[tex]Pound = \frac{2.90 + 1.90}{1.60}[/tex]
Evaluate the sum
[tex]Pound = \frac{4.80}{1.60}[/tex]
