Answer:
A. The number of days Harrison has read since he started the project.
35% decrease as a multiplier = 1 - 0.35 = 0.65
1900 x 0.65^4 = 802.75
$802.75
If you add his expenses, $2.10 + $4.45 you’ll get that Luke spent $6.55 today.
Then subtract his expenses by how much he made for mowing the lawn, $13.50 - $6.55 =
Your answer is A. $6.95
