Answer: 5

explanation: another word for rate of change is slope. to find the slope you count the rise/run (rise over run). that means you count how many units up and how many units across.
(1, -1) is in the corner of a unit box so that’s where i like to start counting from. from there i count up and across until i find another plot that is exactly in the corner of another unit box. the next plot point in the corner of a unit box would be (2, 4). to get to that point i counted 5 units up and 1 unit across.

Aryana wants to invest $43,000. She has two options. Option A gives her 6% compounded quarterly. Option B gives her 6% simple in

solmaris [256]

Answer:

Option A earns higher interest($84115.58)

the difference in interest between the two option is $197.9

Step-by-step explanation:

In the problem we are going to apply both the simple interest formula and compound interest formula and compare which has the best/higher returns

Given data

Principal P= $43,000

Rate r= 6%= 0.06

time t= 3years

n= 4 (applicable for compound interest compounded quarterly)

solving for option A gives her 6% compounded quarterly

the compound interest formula is

$A= P(1+\frac{r}{n} )^n^t\\A= 43000(1+\frac{0.06}{4} )^{4} ^*^3$

$A=43000(1+0.015)^{12} \\A=43000(1.015)^{12} \\A=43000*1.1956\\A= 51411.58$

Interest is $A-P= 51411.58-43000= 8411.58$ =$8411.58

solving for option B which gives her 6% simple interest annually

the simple interest formula is

$A=P(1+r)^{t} \\A=43000(1+0.06)^3\\A=43000(1.06)^3\\A=43000*1.191\\A= 51213.68$

Interest is $A-P=51213.68-43000= 8213.68$ = $8213.68

calculating the diference in interest between the two options we have

$8411.58-8213.68= 197.9$ = $197.9

Option A earns higher interest

WHOEVER ANSWERS FIRST WITH A SERIOUS QUESTION WILL GET BRAINLIEST

shusha [124]

Answer: See Explanation

Step-by-step explanation:

Take the amount of money and divide by the ounces for how much it costs per ounce

1.35 / 12 = 0.1125 per ounce

2.10 / 20 = 0.105 per ounce

3.60 / 32 = 0.1125 per ounce

The Big Swig would be the best deal because the cost per ounce is the lowest, getting you the cheaper price for a good size. I believe I did this right, hope I could help.
