V1=60. 60×t1=50×t2=S
V2=50
T=t1+t2=5. 5-t2=t1
60×(5-t2)=50×t2
300-60×t2=50×t2
300=50×t2+60×t2
300=t2×(50+60)
300=t2×110
300/110=t2

S=50×300/110

KengaRu [80]

Given:

Last month sales = $900

Rate of commission = 20%

To find:

How much commission (in dollars) did she earn last month?

Solution:

We have, 20% rate of commission. So, the commission for the last month is equal to 20% of last month sales $900.

$\text{Commission}=\dfrac{20}{100}\times 900$

$\text{Commission}=20\times 9$

$\text{Commission}=180$

Therefore, the commission for the last month is $180.

Nataliya [291]

Answer:

a) $\frac{3}{20}$ and $\frac{16}{20}$ = $\frac{19}{20}$

b) $\frac{8}{21}$ and $\frac{18}{21}$ = $1\frac{5}{21}$

c) $\frac{18}{72}$ and $\frac{32}{72}$ = $\frac{25}{36}$

Step-by-step explanation:

a) $\frac{3}{20}$ and $\frac{4}{5}$

$\frac{4}{5}$ x 4 = $\frac{16}{20}$

$\frac{3}{20}$ and $\frac{16}{20}$ = $\frac{19}{20}$

b) $\frac{8}{21}$ and $\frac{6}{7}$

$\frac{6}{7}$ x 3 = $\frac{18}{21}$

$\frac{8}{21}$ and $\frac{18}{21}$ = $1\frac{5}{21}$

c) $\frac{2}{8}$ and $\frac{4}{9}$

$\frac{2}{8}$ x 9 = $\frac{18}{72}$

$\frac{4}{9}$ x 8 = $\frac{32}{72}$

$\frac{18}{72}$ and $\frac{32}{72}$ = $\frac{25}{36}$
