Sarah jones earns $525 per week selling life insurance for farmer’s insurance plus 5% of sales over $5,750. sarah’s sales this month (four weeks) are $20,000. how much does sarah earn this month?

$2,812.50

Step-by-step explanation:

Let

y > amount that Sarah earn this month

x > amount of sales over $5,750

we know that

5%=5/100=0.05

The linear equation that represent this situation is

y=4(525)+0.05(x)

Find the value of x

x=20,000-5750=$14,250

substitute

y=4(525)+0.05(14,250)=$2,812.50

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
