To determine the remaining balance, you have to subtract the monthly payment times the number of payments from the purchase price. Speaking mathematically, the equation would be
r = $1350 - $75m
Thus, the answer is letter C.
Step-by-step explanation:
the answer is already as simplified as it could be
Answer:
t = 0.722 seconds
Step-by-step explanation:
Given in the question that an equation
h = -16t² + 6t + 4
here h is the height
t is the time
To solve this question we need to substitute height with zero because at ground level height is zero
<h3>h = 0</h3>
0 = -16t² + 6t + 4
<em>a = -16</em>
<em>b = 6</em>
<em>c = 4</em>
Formula to use
t = -b±√(b²-4ac) / 2a
Plug values in the formula
t = -6 ± √36-4(-16)(4) / 2(-16)
t = 6±2√73 / 32
t = 6+2√73 / 32 or t = 6-2√73 / 32
t = 0.722 or t = -0.347
since time can't be in negative so we reject t = -0.347
Answer:
$30
Step-by-step explanation:
To find the cost, plug in 10 for x, then simplify
1.5x + 15
1.5(10) + 15
= 30
So, it will cost Johnny $30 to download 10 songs
