Chloe works for an estate agent.
Lunna [17]

Answer:

£24,980

Step-by-step explanation:

total pay = monthly salary + percent of annual profit + £250 bonus

monthly salary = £1,850

annual salary = 12 × £1,850 = £22,200

agency income = £356,000

agency costs = £280,000

annual profit = income - costs = £356,000 - £280,000 = £76,000

percent of annual profit = 3% × £76,000 = 0.03 × £76,000 = £2,280

£250 bonus = 2 × £250 = £500

total pay = monthly salary + percent of annual profit + £250 bonus

total pay = £22,200 + £2,280 + £500

total pay = £24,980

True or false 120% of a whole number is always greater than the number? and why?
Stells [14]
I can only use math to explain it. What is 100%?
100% = \frac{100}{100} 
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = \frac{120}{100} * 10 = 12
is it greater than 10.
