The money in your wallet before you pay is 20 dollars

Solution:

At farmers market you buy 4 pounds of tomatoes for three dollars a pound

Cost of 1 pound of tomato = 3 dollars

Therefore,

Cost of 4 pound of tomato = 4 x 3 = 12 dollars

Cost of 4 pound of tomato = 12 dollars

At farmers market you buy 2 pounds of sweet potatoes for two dollars a pound

Cost of 1 pound of sweet potatoes = 2 dollars

Therefore,

Cost of 2 pound of sweet potatoes = 2 x 2 = 4 dollars

Cost of 2 pound of sweet potatoes = 4 dollars

The combined cost spend at market is:

cost spend at market = Cost of 4 pound of tomato + Cost of 2 pound of sweet potatoes

cost spend at market = 12 + 4 = 16 dollars

You spent 80% of the money in your wallet

Therefore, 80% of the money in your wallet is equal to 16 dollars

Let "x" be the money in your wallet

Then, we get

80 % of x = 16


80 \% * x = 16\\\\(80)/(100) * x = 16\\\\0.8x = 16\\\\x = 20

Thus money in your wallet before you pay is 20 dollars
