Answer:
105 for 3 hours
Step-by-step explanation:
First we have to find that how much he is charged for 1 hour.
140 : 4 = 35 per hour
Then we have to find how much he is charged for 3 hours by multiplying with 3.
3 x 35 = 105 per 3 hours
Answer:
£105
Step-by-step explanation:
let y represent the unknown amount
£150 = 4 hrs
y = 3 hrs
we then cross multiply
£150 x 3 hrs = y x 4 hrs
450= 4y
divide both sides by 4
450/4 = 4y/4
105 = y
