Answer:
$367.17
Step-by-step explanation:
we are find the cost of the car after 5 years
Using the compound interest formula;
A = P(1+r/n)^nt
Given
Principal P = $300
rate r = 5.2% = 0.052
Time t = 5years
Time of compounding n = 1/12 (monthly)
Substitute into the formula
A = 300(1+0.052(12))^5(1/12)
A = 300(1+0.624)^0.4167
A = 300(1.624)^0.4167
A = 300(1.2239)
A = 367.17
hence the amount of the car after 5years is $367.17

Answer:
Step-by-step explanation:
Given:
Total number of glasses = 16
Number of glasses containing prune juice = 4
Number of glasses containing apple juice = 2
To find: fractional part of the glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice
Solution:
A fraction refers to the parts of a whole. In a fraction, a top number is the numerator, and a bottom number is the denominator.
Number of glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice = 16 - 4 - 2 = 10
Total number of glasses = 16
So,
Fractional part of the glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice = 
Answer: the store charged $40 for the bike helmet before tax.
Step-by-step explanation:
Let x represent the amount that the store charge for the bike helmet before tax.
If the sales tax rate was 8%, it means that the amount of tax that was charge is
8/100 × x = 0.08 × x = 0.08x
Monica paid sales tax of $3.20 when she bought a new bike helmet. This means that
0.08x = 3.2
Dividing the left hand side and the right hand side of the equation by 0.08, it becomes
0.08x/0.08 = 3.2/0.08
x = 40
Answer:
h(x) = - 4x² + 5
Step-by-step explanation:
To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)
h(x) = - 2(2x² + 1) + 7
= - 4x² - 2 + 7
= - 4x² + 5
