Anfernee bought 4 umbrella and 5 hats and spent between $80.00 and 100.00. each umbrella cost the same amount. each hat cost the same amount. the price of a hat is $4.00. what time s the least amount anfernee could have spent on an umbrella? what is the most anfernee most spent?

$15, $20

Step-by-step explanation:

Let u represent the unit price of umbrellas and h the unit price of hats.

Case 1:  A. spent $80.

Then $80 = 4u + 5($4), or $80 = $20 + 4u, or $60 = 4u, or

u = $15/umbrella.

Case 2:  A spent $100.

Then $100 = 4u + 5($4), or $100 = $20 + 4u, or $80 = 4u, or

u = $20/umbrella.

The least A. could have spent on a single umbrella was $15, and the most was $20.
