Answer:
He will need 14 deliveries to reach his goal.
Step-by-step explanation:
$9/hr x 8hrs = $72.00
$155 - $72 = $83
$83/$6 = 13.83, but he cant make less than a whole delevery, so he would have to make 14 delivers to reach his goal.
The least number of deliveries that Ben must make to reach his goal will be 14.
What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Ben earns $9 per hour and $6 for each delivery he makes.
He wants to earn more than $155 in an 8-hour workday.
Let x be the least number of deliveries that Ben must make to reach his goal.
Then,
[tex]9\times 8 + 6\times 8 \geq 155\\\\72 + 6x \geq 155\\\\6x \geq 155 - 72\\\\6x \geq 83\\\\x \geq 13.83[/tex]
Hence, the least number of deliveries that Ben must make is 14.
