Answer:
a) 198.7% interest
Not too sure about answer to (b)
b) 4.75% annualized
Step-by-step explanation:
a) i used Interest = Principal x Rate x Time
40 = 525 x 
x r
40 = 20.13r
r = 1.987 or 198.7%
b) i used this proportion: 
= 
'x' represents annualized rate
1/24 represents 2 weeks out of a year
1/24x = 1.98
x = 4.75%
Answer:
A- 2x + 8
Step-by-step explanation:
Combine like terms
6x - 4x = 2x. 2x + 8 is left
I think it's :
Part A ; $30 * (x) + $13
$28 * (x) + $15
Part B ; so $30 * 4 + $13 = $133 vs.
$28 * 4 + $15 = $111 so that would mean company B Would charge the least amount.
Part C ; the difference between company a and company B prices is $22.
Answer: 3.33miles
Step-by-step explanation:
given data:
distance covered in first 15 minutes = 10 miles
time spent buying gas and some snacks = 10mins.
= 10/15 * (15 –10 )
= 3.33miles
jacob has traveled 3.3miles between 10 and 15 minutes.
Make an inequality representing both constraints.
0.5x+y<20
x+y≥24
