A discount store had monthly sales of $86,600 and spent 14% of it on promotions. how much was spent on promotion?

Vladimir79 [104]

The amount spent on promotion by the store on monthly sales of $86,600, when they are spending 14 percent on promotion is $12,124.

The percent signifies the hundredth part of the whole.

When informed that the promotion is 14 percent of the monthly sales of $86,600.

Therefore, to calculate the total amount spent on promotion, we calculate 14 percent of 86600.

Therefore, the total amount on promotion = 14% of $86,600 = $ (14/100 * 86,000) = $ (14*866) = $12,124.

Therefore, the amount spent on promotion by the store on monthly sales of $86,600, when they are spending 14 percent on promotion is $12,124.

X is the amount of money that each will pay

2x+(21.50*20/100) =21.50
2x+4.3=21.50
2x=17.2

A family used a professional decorator to help furnish their new home. The decorator selected $1,580 worth of furnishings. In ad

lakkis [162]

Answer:

Step-by-step explanation:

Worth of furnishings = $1580

Tax rate = 4.5%

Tax = 4.5% × $1580 = 0.045 × $1580 = $71.10

Amount paid = $1580 + $71.10 = $1651.10

Since the decorator's fee was 12% of the purchases. This will then be calculated as:

y = kx

where,

y = decorators fee

k = percentage of decorators fee on purchases

x = amount paid

y = 12% × $1651.10

= 0.12 × $1651.10

= $198.132

The approximate equation in slope intercept form is y = 3x + 2.

Solution:

Let us take (0, 2) and (1, 5) on the graph.

$x_1=0, y_1=2, x_2=1, y_2=5$

Equation of the line in slope-intercept form:

y = mx + b

where m is the slope of the line and b is the y-intercept of the line.

Slope of the line:

$$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$$m=\frac{5-2}{1-0}$

$$m=\frac{3}{1}$

m = 3

y-intercept of the line is the value of y when x = 0.

Here the value of y is 2 when x = 0. That is (0, 2) is the point of y-intercept.

Therefore b = 2.

y = 3x + 2

Hence the approximate equation in slope intercept form is y = 3x + 2.
