Answer:
Step-by-step explanation:
1) 144 x $12 = $1728.00
2) $10 x 2 = $20 $20 x 3 = $60 $30 x 2 = 60; $20+$60+$60 = $140
3) $350 - $234 = $116.00
4) $225 ÷ $15 = 15 lawns will need to be cut
5) 2/4 = 1/2 = .50 = 50% B
6) 0.99 + 1.19 + 1.50 + 0.99 = $4.67
7) B 90 seconds is = 1 minutes and 30 seconds (1 minute = 60 seconds)
8) 4 weeks x 5 nights = 20 nights of studying
20 nights x 30 minutes = 600 minutes
600 minutes ÷ 60 (minutes in an hour) = 10 hours of studying D
