Answer:
$260
Step-by-step explanation:
20% is equal to decimal form 0.2 or fraction form 1/5
1/5 of 800 = 1/5 * 800 = 160
He earns 100$ everyday even if he made sales worth $0.
100 + 160 = 260

Answer:
4:5
Step-by-step explanation:
Ratio compares two values. The ratio of nickels to pennies is:

<span>7n + 4 - 5n <= 2(n+2)
Let's simplify these expression first
2n + 4 <= 2(n + 2)
2(n +4) = 2n + 4
The LHS and RHS expressions are the same but the inequality says contrary
Hence 2n + 4 is not less than but equal to 2(n + 2).
7+ 6a >= -4(2-a) - 2a
-4(2-a) - 2a = -8 + 4a - 2a = -8 + 2a. It should be obvious that 7 +6a is greater than the RHS expression.
Suppose a= 2 then we have 7 + 6(2) = 19 while -8 + 2(2) = - 8 + 4 = -4 So it follows that 7 + 6a >= -4(2-4) -2a
4x >= 8. The expression is always true so the equal to option is out.</span>
