25% of 60 to 40% of 30<br> >, < or =

Travka [436]

You can reduce the percentages to fractions:

$25\% = \dfrac{25}{100} = \dfrac{1}{4}$

$40\% = \dfrac{40}{100} = \dfrac{2}{5}$

So, we have

$25\% \text{ of } 60 = \dfrac{1}{4}\cdot 60 = 15$

$40\% \text{ of } 30 = \dfrac{2}{5}\cdot 30 = 12$

kykrilka [37]

Answer:

$2278.846

Step-by-step explanation:

Given the following commision steps :

8% on first $1000;

12% next $2000;

20% on sales above $3000

Recorded sales for a week :

Monday $1500.00

Tuesday $3000.00

Wednesday $ 970.00

Thursday $4563.81

Friday $2760.42

This assu es that commision is calculated after weekly sales:

Total:

(1500 + 3000 + 970 + 4563.81 + 2760.42)

= $12794.23

8% on first $1000

0.08 × $1000 = $80

12% of $2000 = $240

20% of $(12794.23 - 3000)

= 0.2 × 9794.23

= 1958.846

Total commision for the week :

$(80 + 240 + 1958.846)

= $2278.846
