Answer:
part a and part b
Step-by-step explanation:
are not the right answer thx for the points tho
Plugging B into the equation, we get 7.5(25)+(300*5/100)+40=187.5+15+40=
242.5 dollars
For C, since she gets 7.5 dollars per hour, we simply change the 7.5 to 9. Since 7.5 is a number multiplied by a variable, it is a coefficient.
X = 1st evening, y = 2nd evening, z = 3rd evening
x + y + z = 83
x = z + 7
y = 2z
z + 7 + 2z + z = 83
4z + 7 = 83
4z = 83 - 7
4z = 76
z = 76/4
z = 19 <=== 3rd evening calls
x = z + 7
x = 19 + 7
x = 26 <=== 1st evening calls
y = 2z
y = 2(19)
y = 38 <=== 2nd evening calls
