7.50h + 0.20s + 40
variable : a letter subbed in for an unknown number : s and h
coefficient : the number multiplied by the variable : 7.50 and 0.20
constant : just a lone number, no variable attached : 40
Corrine works for 25 hrs and sells 300......h = 25, s = 300
7.50h + 0.20s + 40
7.50(25) + 0.20(300) + 40 =
187.50 + 60 + 40 =
287.50 <===
if she gets a raise and earns 9 per hr...
the coefficient would change from 7.50 per hr to 9.00 per hr. because her pay rate has changed.
the new equation would then be : 9h + 0.20s + 40
Answer: -108/+18 = -6
Step-by-step explanation: Multiply 18 by -6 for B then it simplifies out.
Answer:
no, it'll become -10. 9 will be greater
Step-by-step explanation:
Answer:
a - about 3 packs cause you have to round up
b - $50.76
Step-by-step explanation:
First you divide 42 and 18.
42/18=2.33
You have to round up cause you can't have half of a pack, you can't just buy half of a pack.
So, it is rounded to 3 packs.
Next you have to multiply the number of packs and the cost of each pack of water bottles.
16.92*3=$50.76
a - you have to buy 3 packs
b - the total cost is $50.76
