Add farmers market you buy 4 pounds of tomatoes for three dollars a pound and 2 pounds of sweet potatoes for two dollars a pound. you spent 80% of the money in your wallet right and solve the equation to find how much money is in your wallet before you pay.

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

Thus money in your wallet before you pay is 20 dollars
