What is the average cost of 7 articles if 3 of them cost 30k each and the rest cost 12.5k each

LenKa [72]

${\bold{\red{\huge{\mathbb{QUESTION}}}}}$

what is the average cost of 7 articles if 3 of them cost 30k each and the rest cost 12.5k each

$\bold{ \red{\star{\blue{GIVEN }}}}$

TOTAL NUMBER OF ARTICLE= 7

ARTICLES FOR 30K = 3

ARTICLES FOR 12.5K = 7-3= 4

$\bold{\blue{\star{\red{TO \: \: FIND}}}}$

Average cost of 7 articles

$\bold{ \green{ \star{ \orange{FORMULA \: USED}}}}$

$\red{AVERAGE = \frac{TOTAL \: COST}{ NUMBER \: OF\: ARTICLES }}$

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

$Average \: cost \: of \: 7 \: articles - > \\ \frac{(3 \times 30k) + (12 .5k \times 4)}{7} \\ \frac{90k + 50k}{7} \\ \frac{140k}{7} \\ \blue {Average \: cost \: of \: 7 \: articles - >} \\ 20k$

20:24 is My Answer

Step-by-step explanation:

y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio

proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.

For example 2/5 is Equal to 4/10 this Would be A Example Of a Proportional relationship!

Suppose you loan $320 to a friend and charge them 11% annual interest. If they don't pay you back, how much will they owe you af

RSB [31]

Answer:

Step-by-step explanation:

You want to calculate the interest on $320 at 11% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $320.00.

r is the interest rate, 11% per year, or in decimal form, 11/100=0.11.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 320 × 0.11 × 5 to get that:

The interest is: $176.00

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 320.00 + 176.00 = 496.00. For example:

If you borrowed the $320.00, you would now owe $496.00

If you loaned someone $320.00, you would now be due $496.00
