Correct: Your answer is correct.
(b)
If she had worked all hours as a tutor instead of working both jobs, how much more would she have earned (in dollars)?
$

ahow much did she earn(in dollars)

(a) 13.04 x 7 = 91.28

9.75 x 15 = 146.25

91.28 + 146.25 =237.53

(b) 7 + 15 = 22

13.04 x 22 =286.88

Step-by-step explanation:

she earned 237.53

If she had worked all hours as a tutor instead of working both jobs, she would have made 286.88

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
