Question 4:
Gregory is x years old. Daisy is 2 years older than Gregory. The sum of their ages is 40.
(a) Form an equation in terms of x.
(b) Solve the equation and work out Gregory's and Daisy's ages.

Gregory is 19 years old

Daisy is 21 years old

x +21 =40

125 yards

step-by-step explanation:

i take 75 plus 50.

$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
