Answer:

520 - 303.93 - (10.99 * 4) - 25.25 - 73.43x ≥ 0

-

1) Parentheses

520 - 303.93 - 43.96 - 25.25 - 73.43x ≥ 0

-

2) Combine like terms

146.86 - 73.43x ≥ 0

-

3) Get the variable term alone

-73.43x ≥ -146.86

-

4) Divide to solve

x ≤ 2

** dividing by a negative number, the inequality sign flips **

ANSWER :

x ≤ 2

Step-by-step explanation:

303.93+(4×10.99 )+25.25+73.43x = 520

303.93 + 43.96 + 25.25 + 73.43x = 520

373.14 + 73.43x = 520

73.43x = 520 - 373.14

73.43x = 146.76

x = 146.76 ÷ 73.43

x = 2

x ≤ 2
