Kenji bought 2 hats and an umbrella for $22.oo. the next day he bought 2 hats and 3 umbrellas for $33.00
what is the price of 2 umbrellas?
what is the price of 1 umbrella?
what is the price of 1 hat?
what combination of hats and umbrellas if any, would cost $77.00

33.00 - 22.00 = 11.00 price difference
difference divided by number of umbrellas 11.00/2 = 5.5
The umbrellas are $5.50 each
original cost - cost of umbrella 22 - 5.50 = 16.5
16.5/2 = $8.25 per each hat

8 hats are $66.00 and 2 umbrellas are $11.00
So the combination to equal $77.00 is 8 hats and 2 umbrellas.
