Answer:
(D) 36%
Step-by-step explanation:
Actual cost of truck = $4500
Down payment = $1500
Money left to be paid = 4500-1500 = $3000
A = Monthly payments = 350
n = 10
Principal value (P) = 3000
Using formula,
A=
350 =
= 36% (approx)
Hence (D) is correct.
Answer: Choice D
=====================================================
Explanation:
The left portion is the interval (-∞, -2)
This is a shorthand way of saying
The curved parenthesis says "do not include this endpoint as part of the solution set". Note the open hole at x = -2 in the diagram.
In contrast, the value x = 4 is included (due to the filled in circle), so we use a square bracket for this endpoint. Therefore, the right-hand portion is represented by [4, ∞) which translates to
Negative and positive infinity will always use a parenthesis, and never a square bracket. This is because we can only approach infinity but never reach it, so we cannot include it as an endpoint.
All of this builds up to the full interval notation to be
The only square bracket is near the 4; everything else is a curved parenthesis. This is why choice D is the final answer.
