Abby bought 4 kilograms of heirloom tomatoes, 2.4 kilograms of cherry tomatoes, and 5 kilograms of roma tomatoes. How much did she spend?

vine-ripened tomatoes $3.00 per kg​
roma tomatoes $1.80 per kg​
cherry tomatoes $1.40 per kg​
pear tomatoes $1.61 per kg​
heirloom tomatoes $1.73 per kg​

First, we need to calculate the total cost for each type of tomatoes:

For heirloom tomatoes:
4 kg * $1.73/kg = $6.92

For cherry tomatoes:
2.4 kg * $1.40/kg = $3.36

For roma tomatoes:
5 kg * $1.80/kg = $9.00

Now, we add up the total cost for each type of tomato:
$6.92 + $3.36 + $9.00 = $19.28

Therefore, Abby spent $19.28 in total on the tomatoes.
