Toby buys packs of 12 racing cars for R49,99 and sells each racing car for R10 at school
Ratling [72]

Answer:

1.1  R5.83

1.2 R70.01

1.3 58.34%

Step-by-step explanation:

Given that he buys a pack of 12 racing cars  for  R49,99 then the unit cost for a car which is the total cost divided by the number of cars in a pack

= R49,99/12

= R4.17

If each car is sold for R10 then the profit made on each car which is the difference between the cost and the selling price

= R10 - R4.17

= R5.83

The profit margin on one pack of 12 racing cars

Profit margin is the ratio of the profit to the total selling price

The total profit (profit on one pack of 12 racing cars)

= R5.83 * 12

=R70.01

Total selling price = R10 * 12

=R120

Margin = R70.01 / R120

= 58.34%

The graph of an exponential function has a y-intercept of 7 and contains the point (4,112). Construct the exponential function T
blondinia [14]

The exponential function that describes the graph is y=7\cdot 2^x

The standard form of an exponential function is expressed as y=ab^x

a is the y-intercept

(x, y) is the point on the graph

Given the following expression

a = 7

(x, y) = (4, 112)

Substitute the given values into the exponential equation

y = ab^x\\112=7\cdot b^4\\b^4 = \frac{112}{7}\\b^4= 16\\b =\sqrt[4]{16}\\b = 2

Get the required exponential equation

Recall that y=ab^x, hence the required equation will be y=7\cdot 2^x

T = 320.00 + 0.40b
Gemiola [76]

Answer:

c) The total price for the service  when Terrance's price was equivalent to Sylvester's price  is $600.

Step-by-step explanation:

   Here,   t = 320.00 + 0.40 b

and  t = The total prices charged by Terrance for packing and moving b boxes.

s = 250.00 +0.50 b

and  s = The total prices charged by Sylvester  for packing and moving b boxes.

Now, to find the number of boxes, when both the prices are equal.

⇒320.00 + 0.40 b  = 250.00 +0.50 b

or, 320 - 250 = 0.50 b - 0.40 b

or, 0.10 b =  70

or, b= 70/0.10 = 700

Hence, for packing and moving b = 700 boxes, both companies charge the same amount.

Now, the price charged = 320 + 0.4 (b)

                                         = 320 + 0.4(70) = 320 + 280

                                         = 600

or,  the total price for the service  when Terrance's price was equivalent to Sylvester's price  is $600.

Michelle buys a rug for $36 and sells it for $90. What was the value of her markup, expressed as a percent?
Contact [7]
The markup is 250%, as you just need to divide 90 by 36 and get 2.5, then the whole number is the hundreds, the tenths are the tens and so on.
