Kenna's is earning money. The following equation models her earnings: y=55x+1300

labwork [276]

Answer:

In 14 weeks, they will have the same earnings.

Step-by-step explanation:

y = 55x + 1300 -------- (1)

y = 25x + 1720 -------- (2)

(2) = (1)

55x + 1300 = 25x +1720

55x - 25x = 1720 - 1300

30x = 420

30x ÷ 30 = 420 ÷ 30

x = 14
