$115 per credit hour. gina is taking a combined total of 13 credit hours at the two schools.
suppose that she is taking w credit hours at westside. write an expression for the combined total dollar amount she paid for her class fees.
total paid = 213w
total paid = -17w + 1495
total paid = 98w + 115
total paid = 98 (13 - w) + 115

second option.

Step-by-step explanation:

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

c-   36
