Monty invested 8600 in a savings account with a yearly interest rate of 5% for 12 years how much simple interest did he earn

Simple interest = $5,160

Step-by-step explanation:

Given: Monty invested 8600 in a savings account with a yearly interest rate of 5% for 12 years.

Formula:

where, P is principle (P=8600)

R is rate of interest (R=0.05)

T is time period (T=5)

I is simple interest (I=?)

Therefore,

Hence, The simple interest in 12 years is $5,160

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
