A textbook store sold a combined total of 435 psychology and sociology textbooks in a week. The number of sociology textbooks sold was 61 less than the number of psychology textbooks sold. How many textbooks of each type were sold?

248 psych books, 187 soc books.

Step-by-step explanation:

x psych books were sold

x-61 soc books were sold

Total books was 435.

So -

x+x-61 = 435

2x-61 = 435

2x = 496

x = 248.

so x-61 = 187 and

248+187 = 435.

248 psych books, 187 soc books.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
