A company wants to purchase two types of lightbulbs, CFL (compact fluorescent) and LED (light emitting diode). The cost of each CFL bulb is $2, and the cost of each LED bulb is $20.
The company must purchase a total of 800 lightbulbs, must spend at most $5,000 on the lightbulbs, and wants to
purchase as many LED bulbs as possible.
Let L represent the number of LED lightbulbs purchased, and C represent the number of CFL lightbulbs purchased.
Which of the following systems models the situation described?
2C + 20L - 800
C+L < 5,000
B
20C + 2L = 800
C + L < 5,000
20 + 20L < 5,000
C + L = 800
200 + 2L < 5,000
C+L - 800

b

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
