Answer:
The inequality should be written as $2.50 times c is greater than or equal to c.
Step-by-step explanation:
First, identify what you know:
1) Each chocolate bar is $2.50
2) Sebastian needs to raise at least $500
So, Sebastian needs to sell at least enough chocolate bars to hit $500. The inequality cannot be written as less than or equal to, because he can't sell less than the number of chocolate bars needed to make $500.
Automatically, I can calculate the minimum number of bars he'll need to sell.
500/2.50 = 200 chocolate bars minimum
c must equal greater than or equal to $500, for Sebastian to raise enough money! So, basically Sebastian has to sell 200 bars OR more.
Hope this helps! :)

Answer with explanation:</h2>
1. Let x = Number of nickels
y= Number of quarters
Equation:
(i)
Equation:
(ii) [∵ 1 nickel = $0.05 , 1 quarter = $0.25]
Multiply equation (ii) by 20, we get
(iii)
Eliminate (i) from (iii), we get
![4y=40\Rightarrow\ y=10](https://tex.z-dn.net/?f=4y%3D40%5CRightarrow%5C%20y%3D10)
put y= 10 in (i) ,
![x+10=20\Rightarrow\ x=10](https://tex.z-dn.net/?f=x%2B10%3D20%5CRightarrow%5C%20x%3D10)
Sentence = " Jane has 10 nickels and 10 quarters".
2. Let x = Number of dimes
y= Number of nickels
Equation:
(i)
Equation:
(ii) [∵ 1 nickel = 5 cents, 1 quarter = 25 cents]
Multiply equation (i) by 5, we get
(iii)
Eliminate (iii) from (ii), we get
![5x=15\Rightarrow\x=3](https://tex.z-dn.net/?f=5x%3D15%5CRightarrow%5Cx%3D3)
put x=3 in (i) ,
![3+y=12\Rightarrow\ y=9](https://tex.z-dn.net/?f=3%2By%3D12%5CRightarrow%5C%20y%3D9)
Sentence = " Joey has 3 dimes and 9 nickels".
Answer:
x = 5/42 or 0.119
Step-by-step explanation:
log(6x) + log(14) = 1
log(6x × 14) = 1
log(84x) =
84x = 10¹
84x = 10
x = 10/84
x = 5/42 or 0.119
