Help with number 3 ,4, 5

Calculate the amount of interest you'll have at the end of the indicated period.

Alexeev081 [22]

Answer:

$160

Step-by-step explanation:

I = 800 * 5 * 4% (I multiply the time and principal first, so I already have the wholes covered.)

I = 4,000 * 4% (now to convert 4% and 4000 into fractions.)

I = 4000/1 * 1/25 (Cross cancel if needed. GCF is 25.)

I = 160/1 * 1/1 (Just remove 1/1)

I = $160 (There's your answer!)

Mae Ling earns a weekly salary of $315 plus a 5.5% commission on sales at a gift shop. How much would she make in a work week if

Alecsey [184]

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Step-by-step explanation:

The given is:

Mae Ling earns a weekly salary of $315 plus a 5.5% commission on sales at a gift shop
She sold by $4,700

We need to find how much she would make in a work week

∵ Mae Ling earns a weekly salary of $315

∵ She earns a 5.5% commission on sales

∵ She sold by $4,700 in that week

- Add $315 to the product of 5.5% and $4,700

∴ She made = 315 + (5.5% × 4,700)

∵ 5.5% = 5.5 ÷ 100 = 0.055

∴ She made = 315 + (0.055 × 4,700)

∴ She made = 315 + 258.5

∴ She made = 573.5

She would make $573.5 in a work if she sold $4,700 worth of merchandise

What is the area of a parallelogram if its length is x+4 and its height is x+3

lord [1]

Area of a parallelogram is:

$\sf A=bh$

Where 'b' is the base and 'h' is the height. Plug in what we know:

$\sf A=(x+4)(x+3)$

Distribute(multiply everything in the first parenthesis to everything in the second parenthesis):

$\sf x\times x=x^2$
$\sf x\times 3=3x$
$\sf 4\times x=4x$
$\sf 4\times 3=12$

So we have:

$\sf A=x^2+3x+4x+12$

Combine like terms(3x + 4x = 7x):

$\sf A=\boxed{\sf x^2+7x+12}$

Problem 2

Brilliant_brown [7]

Answer:

Let the 'cart' total is x and total payment is y.

The sales tax is 5.6% added to the 'cart' amount and then shipping and handling fee added.

<u>There are three intervals as below and function added accordingly:</u>

0 < x ≤ 49.99 ⇒ y = x + 5.6% + 3.95 = 1.056x + 3.95
50 ≤ x ≤ 75.99 ⇒ y = x + 5.6% + 11.95 = 1.056x + 11.95
x ≥ 76 ⇒ y = x + 5.6% + 5.95 = 1.056x + 5.95

x = 74.50, this falls in the second interval
y = 74.50*1.056 + 11.95 = $90.62 (rounded )

y = 89.20, this is close to the number we got in part B and we assume it is same - the middle interval.

89.20 = 1.056x + 11.95
1.056x = 89.20 - 11.95
1.056x = 77.25
x = 77.25 / 1.056
x = 73.15 (rounded )

-----------------------------------------

<em>Note. Shipping and Handling charges seems incorrectly ordered. If so the answers above all should change accordingly.</em>
