question
erica earned a total of $50,450 last year from her two jobs. the amount she earned from her job at the store was $1,250
more than four times the amount she earned from her job at the college. how much did she earn from her job at the
college?

$9,840

Step-by-step explanation:

Let the money earned from college be 'x'.

Therefore, the money earned by Erica from her job at the college is $9,840.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
