Answer:
a) 395.725
b) 378.75
c) 8.8
Step-by-step explanation:
a) S(8.5) = 11.25(8.5) + 300 = 395.625
b) if she worked 47 hrs, that means there were 7 overtime, h=7 and we have to find S(7).
S(7) = 11.25(7) + 300 = 378.75
c) her salary was 398.61, that means S(h) = 398.61 and we have to find h.
398.61 = 11.25(h) + 300
98.61 = 11.25(h)
h = 98.61 / 11.25
h= 8.8
Answer:
2x+3=-13
x=5
Step-by-step explanation:
it says 2 times a number which would be the 2x, and it says the sum of that and 3 which would be 2x+3 and it says is 13. 2x+3=13
now solving it
2x+3=13
subtract 3 from both sides
2x=10
and divide 2 from both sides
x=5
