7. David has saved $300 to buy a new TV. If the TV he wants costs $1,200 and he saves $10 a week, howmany years will it take him to buy the TV?a. 3 yearsb. 1 yearc. 2 yearsd. 4 years

Respuesta :

First, we subtract the $300 he has saved already from the cost of the TV

That is; $1200 - $300 = $900

Since he saves $10 per week

To get the number of weeks it will take to save $900, divide $900 by $10

The result is 90 weeks

It will take him 90 weeks to save $900

But 52 weeks = 1 year

104 weeks = 2 years

This implies that; 90 weeks falls under 2 years

Therefore, It will take David 2 years to buy the TV

The correct option is C. 2 years
