price of one message = 1.35 ÷ 9

1.35 ÷ 9 = 0.15

0.15 • 118 = ( 3 ÷ 20 ) • 118

118 • 3 = 354

354 ÷ 20 = 177 ÷ 10 = $17.7 to send 118 messages

Assume that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles
OverLord2011 [107]

Answer:

Final answer is approx 6.644 years.

Step-by-step explanation:

Given that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles is 16% every year and that of cars is 25% every year.

So we can use growth formula:

A=P\left(1+r\right)^t

Then we get equation for motorcycles and cars as:

A=5.75\left(1+0.16\right)^t

A=3.5\left(1+0.25\right)^t

Now we need to find about when the sale of cars will be more than the sale of motorcycles. So we get:

3.5\left(1+0.25\right)^t>5.75\left(1+0.16\right)^t

3.5\left(1.25\right)^t>5.75\left(1.16\right)^t

3.5\left(1.25\right)^t>5.75\left(1.16\right)^t

\frac{\left(1.25\right)^t}{\left(1.16\right)^t}>\frac{5.75}{3.5}

\left(\frac{1.25}{1.16}\right)^t>1.64285714286

t\cdot\ln\left(\frac{1.25}{1.16}\right)>\ln\left(1.64285714286\right)

t>\frac{\ln\left(1.64285714286\right)}{\ln\left(\frac{1.25}{1.16}\right)}

t>6.6436473051

Hence final answer is approx 6.644 years.

Charley's grade in the three quarters are 85, 88, and 92. If she targets to have an average
topjm [15]

Step-by-step explanation:

We can set up an average equation in the form, where x is the last score in the fourth quarter:

\frac{85 + 88 + 92 + x}{4} = 90

85 + 88+92 + x =360\\\\x = 95

She needs at least a 95 on the last quarter to average 90 in all four quarters.

tim has $45. he buys pens that cost 2.75 each until he has only 12.00 left. if x represents the number of pens purchased.. write
aliya0001 [1]

Solve this equation:  $45 - ($2.75/pen)x = $12.  Simplifying, we get

$33 = ($2.75)x, so that

x = $33 / ($2.75) = 12.

Tim's buying 12 pens leaves him with $12.
