Answer:

39 child tickets

Step-by-step explanation:

Let x represent the number of child tickets sold,

let y represent the number of adult tickest sold.

"three times as many adult tickets as child tickets were sold," becomes

x = y/3 x is one-third the value of y

"$5.80 and adult admission is $9.20" and " for a total sales of $1,302.60" become

$5.80x + $9.20y = $1,302.60

We know that x = y/3, so substitute that into the second equation...

$5.80(y/3) + $9.20y = $1,302.60

Now solve for y...

$5.80y + $27.60y = $3,907.80 (multiply by 3 to get rid of the fraction)

$33.40y = $3,907.80 (combine like terms)

y = $3,907.80/$33.40 (divide both sides by $33.40 to isolate y)

y = 117

If there were 117 adult ticket sold, then there were

x = 117/3 child tickets

x = 39 child tickets

Compute the exact interest on $5,870 at 12% if the money is borrowed from June to December of the same year.

yawa3891 [41]

Answer:

The exact interest on $5,870 at 12% is $410.9

Step-by-step explanation:

From the information provided we know that

Principal amount: $5,870

Interest rate: 12% -> 0.12

Time: 7 months (From June to December)

When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula:

$I=P\cdot r\cdot t$

where P is principal, r is the rate of interest and t is the time in years.

We need to convert the 7 months into 1 year.

$7 \>months \cdot \frac{1 year}{12 months} = \frac{7}{12} year$

Now we can use the above formula

$I=P\cdot r\cdot t=5870\cdot 0.12 \cdot \frac{7}{12} \\I = 0.12\cdot \frac{7\cdot \:5870}{12}\\I = 0.12\cdot \frac{20545}{6}\\I = \frac{2465.4}{6}\\I = 410.9$

Therefore the exact interest on $5,870 at 12% is $410.9
