1. Jared borrowed $300 from his mother to buy an x-box 360. Jared will pay her back in 4 years with 3.5% simple interest. How mu

BigorU [14]

Answer:

1) future value = present value x [1 + (i x n)] = $300 x [1 + (3.5% x 4)] = $342

2) using the compound interest formula:

future value = $225 x (1 + 4.1%)¹°⁵ = $238.98

Using the simple interest formula doesn't yield the same answer = $225 x [1 + (4.1% x 1.5)] = $238.84. In this case it is close due to a very short period of time and low interest rate.

3) future value = present value x (1 + i)ⁿ = $1,700 x (1 + 6%)⁴ = $2,146.21

since the interest is annual, we must convert 48 months to 4 years

Two planes simultaneously left the Washington and LA and headed towards each other. The distance between the cities is 2700 mile

katrin2010 [14]

Answer:

Speed of the plane from Washington: $500\ mph$

Speed of the plane from LA: $600\ mph$

Step-by-step explanation:

We need to remember that:

$d=Vt$

Where "d" is distance, "V" is speed and "t" is time.

Let be "w" the speed in mph of the plane from Washington and "l" the speed in mph of the plane from LA.

We know that the distance between the cities is 2700 miles and after they flied for 2 hours, the distance between them was 500 miles. Then we can write the following equation:

$2w + 2l + 500 = 2700$ [Equation 1]

Since the speed of the plan from LA was 100 mph faster, we can write this equation:

$l=w+100$ [Equation 2]

The steps to solve this are:

1. Substitute the Equation 2 into the Equation 1 and solve for "w":

$2w + 2(w+100) + 500 = 2700\\\\4w+200+500=2700\\\\w=\frac{2000}{4}\\\\w=500$

2. Substitute the value of "w" into the Equation 2 in order to find "l":

$l=500+100\\\\l=600$

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

An inequality shows the non equal comparison of two or more numbers and variables.
