The speeds (s) of a car varies partly as its mass (m) and partly directly as the quality (q) of a fuel in it. when the speed is 80km/h the mass 220kg ang the quality of fuel is 30 litre, when the speed is 60km/hr, the mass is 360 kg and the quantity of fuels 40 litres. Find the value of fuel if the speed is 100km/h and the mass kg.

the answer is 21%.

$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
