Sam wants to attend a 2-year technical college that charges about $3,200 a year. His grandparents said they will
give him half the cost of the tuition each year. Sam wants to save money while working at his summer job for
the next five years. How much money will he have to save each summer to have enough money for his first
year's college tuition?

$320

Step-by-step explanation:

Given parameters:

  Cost of attending the 2-year technical college = $3200;

 His parents intend to give him half the cost;

      Half the cost  = x $3200 = $1600

The remaining cost  = $3200 - $1600 = $1600

Sam has 5yrs to work every summer;

  He must save:  = $320 every summer for the next five years to afford his first year tuition

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
