will works 7 hours a day, 6 days a week. he is paid 9.20 an hour. he shares is wages with his mum in the ratio will:mum 5:2

Answer:

7 weeks.

Step-by-step explanation:

Will works 7 hours a day, 6 days a week. So total number of hours worked by Will is,

[tex]=7\times 6=42[/tex] hours

He earns £9.20 an hour, so total money earned in a week by Will will be,

[tex]=42\times 9.20=\£386.4[/tex]

As he shares with his mother in a ration of 5:2, so he gets 2 parts out of 7 parts. (as 5+2=7)

So the actual amount saved by Will is,

[tex]=386.4\times \dfrac{5}{7}=\£276[/tex]

The price of the car is £1932, so the number of week that Will will take is,

[tex]=\dfrac{1932}{276}=7[/tex]
