Annual rate = 1.05%
Simple interest formula is I = Prt * 100
Where P is principle, I is interest, r is rate and t is time.
Transpose to make r the subject
Prt * 100 = I
r = I/ Pt * 100
Substitute values into the equation.
Let I = $1260, P = $30,000 and t = 4 years
r = $1260/ $30,000 * 4 * 100
r = 0.0105 * 100
r = 1.05%

Step-by-step explanation:
<u>Given the equation: </u>
- E - weekly total, g- number of hours at gas station, t- number of hours at toy store.
<u>Substitute given values into equation and solve for the missing one:</u>
- 219.75 = 9.25g + 10.5*13
- 219.75 = 9.25g + 136.5
- 9.25g = 219.75 - 136.5
- 9.25g = 83.25
- g = 83.25/9.25
- g = 9
Sydawna works 9 hours at the gas station
Answer and step-by-step explanation:
20. Because the discount is 20% of the given price so the discount would be"
228/100*20
= 45.6 Rs
Its selling price would be:
228 + 45.6 = 273.6 Rs
21. Sales tax would be:
450/100*5
= 22.5 Rs
Total price in bill = 22.5 + 450 = 472.5 Rs
22. 10% tax of 3300 would be:
3300/100*10 = 330 Rs
Price before tax = 3300 - 330 = 2970 Rs
23. He spent in total of:
2500 + 500 = 3000Rs
He sold for 3300 Rs
He gain 3300 - 3000 = 300 Rs profit
His loss gain percent = 3300/3000 * 100 = 110%
24. On the first bike, he earn:
2500/100*20 = 500 Rs
On the second bike, he lose:
2500/100*25 = 625 Rs
He lose in total of 625 -500 = 125 Rs
his loss percentage = (2500+500) + (2500 - 625) / 5000* 100
= 100% - (2500+500) + (2500 - 625) / 5000* 100
= 100% - 97.5%
He lose 2.5% money
