A school is in session for 6 hours each day. Each class is allotted 3/4 hour, including passing time. How many classes can be fit into the school day?
<span>6 / (3/4) = </span>
<span>6 * (4/3) = 24/3 = 8 classes</span>
Answer:
90% Solution
Step-by-step explanation:
5% of 90 + 90% of x = 75% of (90 + x)
5×90/100 + 90x/100 = 75×90/100 + 75x/100
Or 90x/100 - 75x/100 = 75×90/100 - 5×90/100
Or 15x/100 = 90×70/100
Or X = 420ml
You Will Need ML Of The 90% Solution To Obtain ML Of The Desired 75% Solution.

Based on the information, Christian would have $5525.5 of annuity.
<h3>How to calculate the annuity?</h3>
According to given information, the number of coffees per week is 3 then, per month is 3x4 = 12
For each coffee is $4.5. Then monthly expenditure for coffees is 12 x 4.5 = $54
Rate of interest r = 1.6% = 1.6/100 = 0.016 and for monthly compounding r = 0.016/12 = 0.00133
n = number of payments = 8 x 12 = 96
We can use the formula for finding the future value as below
FV = C x [ ( 1 + r )n-1 ] / ( r )
FV = 54 x [ ( 1 + 0.00133 )96 – 1 ] / (0.00133)
= 54 x [ (1.13609 - 1)] / (0.00133)
= 54 x 0.13609 / (0.00133)
= 54 x 102.3233
= 5525.5
Therefore Christian would have $5525.5 of annuity.
