Adam earned a total of £265.10 last week.
Step-by-step explanation:
Step 1; Adam earns a basic pay of £200 each week. He earns 10% of the magazine price for each sold and 15% of the book price for each sold. Each magazine costs £8 and each book costs £15. He sells 42 magazines and 14 books.
Money earned for selling a magazine = 10% × £8 = 0.10 × £8 = £0.80,
Money earned for selling a book = 15% × £15 = 0.15 × £15 = £2.25,
Money earned for selling 42 magazines = 42 × £0.80 = £33.60,
Money earned for selling 14 books = 14 × £2.25 = £31.50,
Money earned for selling 42 magazines and 14 books = £33.60 + £31.50 = £65.10.
Step 2; Now we have to calculate his last week's salary which is his weekly pay and his earnings from selling magazines and books. We found that he earned £31.50 from selling books and magazines. His weekly salary is £200.
Last week's salary = £200 + £65.10 = £265.10.
72 and 45 can both be divided by 3.
So,
72 + 45
= 3 (24 + 15)
Answer:
(-8,-1)
Step-by-step explanation:
Answer:
f(5) = 17
Step-by-step explanation:
Using the recursive rule and f(1) = 5 , then
f(2) = f(1) + 3 = 5 + 3 = 8
f(3) = f(2) + 3 = 8 + 3 = 11
f(4) = f(3) + 3 = 11 + 3 = 14
f(5) = f(4) + 3 = 14 + 3 = 17
This is the concept of algebra, we are required to subtract the complex numbers. Thus;
(5-2i)-1(1+8i)
opening the brackets using the distributive property we get:
5-2i-1-8i
collecting the like terms we get:
5-1-2i-8i
=4-10i
the answer will therefore be:
4-10i
