1st way

To solve this we need to know ratio.

$- \frac{1}{5} \div \frac{1}{5} = - 1 \\$

Now we can see that odd numbers of geometric sequence are positive and even numbers are negative. 91 - odd number, so it will be positive. If ratio is equal to -1, than 91st number is

$\frac{1}{5} \\$

2nd way

Firstly, we need to find ratio.

$- \frac{1}{5} \div \frac{1}{5} = - 1 \\$

Secondly, we need to use this formula

$b_n=b_1 \times q^{n-1} \\$

$b_{91}= \frac{1}{5} \times ( - 1)^{91-1} = \frac{1}{5} \\$

A salesperson sells $3600 in merchandise and earns a commission of $576. Find the commission rate.

Kitty [74]

Total sales = $3600

Commission earned on $3600 = $576

Commission rate can be calculated as = $\frac{576}{3600}\times100$

= 16%

Hence, commission rate is 16%

Estimate using rate per 100. 24% of 289

sdas [7]

Estimate using rate per 100. 24% of 289

Solution: We have to find the 24% of 289,

We know that:

$24\%=\frac{24}{100}$

$\therefore 24\% of 289 = \frac{24}{100} of 289$

$=\frac{24}{100}\times289$

$=0.24 \times 289$

$=69.36$

$\therefore 24\% of 289 = 69.36$
