To solve this problem, we need to determine the value of x, which represents the number of phone repairs performed by Care and Rick.
Let's break down the information given:
Cost of phone repair: $11
Number of phone repairs: x
Cost of laptop repair: $15
Number of laptop repairs: 2
Cost of computer repair: $18
Number of computer repairs: 2
Total earnings for the week: $121
We can set up the equation as follows:
Cost of phone repair * Number of phone repairs + Cost of laptop repair * Number of laptop repairs + Cost of computer repair * Number of computer repairs = Total earnings for the week
$11x + $15 * 2 + $18 * 2 = $121
Let's simplify and solve for x:
$11x + $30 + $36 = $121
$11x + $66 = $121
To isolate x, we subtract $66 from both sides of the equation:
$11x + $66 - $66 = $121 - $66
$11x = $55
To solve for x, we divide both sides of the equation by $11:
x = $55 / $11
x = 5
The value of x is 5.
#### 5
The answer is: 5
