Answer:
7.06 × 10^5
Step-by-step explanation:
Cost function=fixed cost + variable cost
=400+(something)
okay let's think
we can only sell q shirts per week
and each shirt cost us 4 dollars
so i think the Cost function
=400+4q
=400+4(-40x+800)
=400-160x+3200
=-160x+3600
but i'm not sure of the this terminology
It's a because 5 divided by 9 equals .555555555555556. The 6 is just from rounding the number. Otherwise the five would go on forever. The bar means go on forever. So it .5 with a bat over the 5
Answer:
The reciprocal of -7/9 is -9/7
Step-by-step explanation:
A reciprocal of a number is the multiplicative inverse of said number. In other words,
The reciprocal of x/y is y/x
Therefore, the reciprocal of -7/9 is -9/7
Answer:
The fan = x = 400
The heater = y = 3600
Step-by-step explanation:
Let the cost price of
The fan = x
The heater = y
Aaya bought a fan and a heater for Rs 4,000.
x + y = 4000
x = 4000 - y
He sold the fan at a profit of 25%
25% × x = 0.25x
And the heater at a loss of 5%.
5% × x = 0.05y
If he gained 7% on his total outlay, at
Hence:
0.25x + 0.05y = 7% × 4,000
0.25x + 0.05y = 280
Note:
x = 4000 - y
Hence:
0.25(4000 - y) + 0.05y = 280
1000 - 0.25y + 0.05y = 280
Collect like terms
-0.25y + 0.05y = 280 - 1000
-0.20y = -720
y = -720/0.20
y = 3600
x = 4000 - y
x = 4000 - 3600
x = 400
Hence, the price that he bought each item is given as:
The fan = x = 400
The heater = y = 3600
