Answer:
$120
Step-by-step explanation:
Job1:
    To find the tax, multiply the payment per week ($70) by 0.1.
     Tax = payment * tax rate
        = 70 * 10%
        [tex]\sf = 70 * \dfrac{10}{100}\\\\ = \$7[/tex]
Now, to find his earning after deduction of tax, subtract 7 from 70.
Amount after deduction of tax = 70 - 7
                         = $ 63
Job2:
    Tax = 60 * 5%
       = 60 * 0.05
        = $3
 Amount after deduction = 60 - 3
                      = $ 57
Total amount Byron takes home = 63 + 57
                           = $120
