Given that:
Charge per car = $8.50
Averahe car washed per weekend = 22
Using front end estimation, how much will business earn in 5 weeks ;
Hence amount earned per weekend :
22 * $8.50 = $187
Using front end estimation :
$187 - - -> $200
$200 * number of weeks
($200 * 5) = $1,000

Step-by-step explanation:
<u>Step 1: Define</u>
5(w + 2.2) - 4w = 9.3
<u>Step 2: Solve for </u><em><u>w</u></em>
- Distribute 5: 5w + 11 - 4w = 9.3
- Combine like terms: w + 11 = 9.3
- Isolate <em>w</em>: w = -1.7
<u>Step 3: Check</u>
<em>Plug in w into the original equation to verify it's a solution.</em>
- Substitute in <em>w</em>: 5(-1.7 + 2.2) - 4(-1.7) = 9.3
- (Parenthesis) Add: 5(0.5) - 4(-1.7) = 9.3
- Multiplication: 2.5 + 6.8 = 9.3
- Addition: 9.3 = 9.3
Here we see that 9.3 does indeed equal 9.3.
∴ w = -1.7 is the solution to the equation.
