Answer :
After buying three kilos of pears, two kilos of tomatoes, and two kilos of papaya, Doña María received $79 in change from her two $50 bills.
To calculate the change Doña María received, we first need to determine the total cost of the items she bought.
Let's assign a cost per kilo for each item:
Pears: Let's say they cost $3 per kilo.
Tomatoes: Let's say they cost $2 per kilo.
Papaya: Let's say it costs $4 per kilo.
Now, calculate the total cost:
Pears: 3 kilos * $3/kilo = $9
Tomatoes: 2 kilos * $2/kilo = $4
Papaya: 2 kilos * $4/kilo = $8
Total cost = $9 + $4 + $8 = $21
Doña María paid with two $50 bills, so the total amount she gave is 2 * $50 = $100.
To find the change, subtract the total cost from the amount paid:
Change = $100 - $21 = $79
Therefore, Doña María received $79 in change.
