Answer:
decreased by 220 dollars
Answer:
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
