Alex works 4 hours on tuesday,thursday ,and Friday.He earns $6.50 per hour.He is saving to buy a television that costs $525.How many weeks will Alex have to work to buy the television?

I assume he works 4 hours on each of those days.

4 * 3 * 6.5 = $78 per week

525 / 78 = _______ weeks

6 weeks

To find out how many weeks Alex will have to work to buy the television, we need to calculate his total earnings, and then divide it by his weekly earning.

First, let's calculate Alex's weekly earning. Alex works for a total of 4 hours on Tuesday, Thursday, and Friday, which means he works for a total of 3 days per week. Since he earns $6.50 per hour, his weekly earnings can be calculated as follows:

Earnings per day = $6.50/hour × 4 hours/day = $26 per day
Weekly earnings = Earnings per day × 3 days/week = $26 × 3 = $78 per week

Now, we can divide the cost of the television ($525) by Alex's weekly earnings ($78) to find out how many weeks he will need to work:

Number of weeks needed = $525 / $78 ≈ 6.73

Since we cannot have a fraction of a week, we round up the number of weeks to the nearest whole number: 7.

Therefore, Alex will need to work for approximately 7 weeks to buy the television.
