Sue spend 56 minutes in reading.
<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Sue spent 1 hour 19 minutes less than Jared
Lucas spent 45 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Jared spent
= 3 hours or (180 minutes) - 45 minutes
= 2 hours 15 minutes.
Now, Seu spent = 2 hrs 15 minutes - 1 hour 19 minutes
= 56 minutes

3 should be added to the tiles
You would solve this with simultaneous equations, so if we write it as:
5n + 2p = 9
3n + 2p = 6
(subtract)
2n = 3
÷ 2
notebooks = 1.5
Now you would substitute it in:
(3 × 1.5) + 2p = 6
4.5 + 2p = 6
- 4.5
2p = 1.5
÷ 2
pens = 0.75
So your final answer is notebooks are $1.50 and pens are $0.75, I hope this helps!

Based on the information given, the simple interest rate that will be earned will be 13.6%.
- Principal = $5250
- Simple Interest = $6500- $5250 = $1250
- Time = 21 months = 1.75 years.
Simple Interest = PRT / 100
1250 = (5250 × 1.75 × R) / 100
Cross multiply
125000 = 9187.5R
R = 125000 / 9187.5
R = 13.6%
