I think it would be A.
hopefully this helped ᵔᴥᵔ
if it did dont forget to mark brainliest
The sum of five and the quotient of two and four
because u do division first
Answer:
1. It should be 7
2. They have $46
Step-by-step explanation:
1. You make a system of linear equations from this. So it would be y= 5x+11 where x is the number of weeks and y is the money. And the second linear equation is y=-2x+60. Then you substitute it. You make it 5x+11=-2x+60. Then you solve it normally and you got your answer but remember in this case they are asking for the x. So make sure to submit the x and not the y.
2. For this it is the same thing except they are asking for the y not the x.
There are two types of interest: Simple interest and compounding interest:
Simple interest: F = P(1+in)
Compounding interest: F = P(1+i)ⁿ
The compounding interest is always bigger than simple interest for a given amount of n time. The effective interest rate is
Effective interest rate = 1.5%/year * 1 yr/12 months = 0.125% per month
Since there are 12 months in 1 year, n= 12. Then i = 0.125/100 = 0.00125
Difference = Compounded Interest - Simple Interest
Difference = P(1+i)ⁿ - P(1+in) = 1000(1+0.00125)¹² - 1000(1+0.00125*12)
Difference = $0.104
You will only have $0.104 more money than the simple interest.
