i dont fully understand this and got help from my math teacher, and she lead me to the answer, so im pretty sure these are correct
Jenna= $15 per hour
Susan= $11 per hour
I think that this is right.... but I am not REALLY sure....... hopefully this is correct.
Answer:
175.
Step-by-step explanation:
40 = 2*2*2*5
1400 = 2*2*2*5*5*5*7
So by inspection we have x = 5*5*7 = 175
There are 52 weeks in one yer.
Multiply the amount spent in one week by 52 to get the yearly total
12.55 x 52 = 652.60 per year
If you spend 10 per week, multiply that by 52 to find the total savings.
10 x 52 = 520 per year.
To find the savings subtract the two totals:
652.60 - 520 = 132.60 savings.
