Aril and Dita are wealthy Norwegian business owners who make monthly donations to international
disaster relief.
Aril donated 150 Norwegian kroners (kr) the first month, and the cumulative number of Norwegian
kroners she has donated increases by a factor of 2.5 each month.
• Dita donated 300 kr the first month, and the cumulative number of Norwegian kroners she has
donated increases by 400 kr each month.
They started making donations at the same time, and they both make their monthly donations at the
beginning of each month.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

$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
