To find the answer we have to calculate total tickets.
We know that 13 students sold 150 tickets and rest sold 60 each.
First I want to find ticket sold by 13 student, so
13*150=1950
Rest of class is 24-13=11
Ticket sold by rest of class is
11*60=660
Total sold ticket is
1950+660=2610 they rich their goal

Answer:
The annual interest rate was 5.25%.
Step-by-step explanation:
Simple interest can be calculated using the following formula: I = PRT, where I=simple interest, P=principal amount, R=percentage rate and T=time. In this problem, Mona started with a principal amount of $2840, or P=2840 and invested for 6 years, or T=6, to gain simple interest in the amount of $894.60, or I=894.60. When we put in the values for our variables in the equation, we get: 894.60 = (2840)(6)R. Multiplying 2840 x 6 = 17040 and gives us: 894.60 = 17040R. Using inverse operations to isolate the variable, we divide both sides by 17040 to get R=0.0525. Since the rate is a percentage, we need to multiply our answer by 100 to get 5.25%.
