Help please I don't need help on number 2 but I don't understand #1

The value on her gift card decreased by $220 dollars.

Step-by-step explanation:

We don't know what amount she originally had on the card, but we can still find out how much she lost by adding up the prices of the things she bought/rented. First, we need to find the cost of renting the tiller for 6 days, it costs $36 per day, so we need to do 6 times 36, which gives us $216. Then we need to add the $4 for the rake.

$216 + $4 = $220
