Answer:

[tex]part \: a. \\ t = 300+300(13) = 300+300C = \\300 + 3,900 = 4,200 \\ t = 4,200[/tex]

[tex]part \: b. \\ 3300 = 300+300(c) \\ 3300 - 300 =300(c) \\ 3000 \div 300 = c = 10 \\ c = 10[/tex]

  • The tuition cost for 13 credits is $4,200.
  • And, the number of credits that are taken is 10.

a.

The tuition cost for 13 credits is

= 300 + 300C

= 300 + 300 (13)

= 300 + 3900

= 4,200 dollars.

b.

And, the number of credits is

$3,300 = 300 + 300C

$3,300 - 300 = 300C

$3,000 = 300C

C = 10 credits

Therefore we can conclude that

  • The tuition cost for 13 credits is $4,200.
  • And, the number of credits that are taken is 10.
