Your hourly salary increased from $14 to $29. What is the percent increase in your<br> salary?
V125BC [204]

Answer:

107%

Step-by-step explanation:

$14 to $29

Original number/start = $14

End number = $29

Increase = $29 - $14 = $15

% increase = Increase ÷ Original Number × 100

Substitute in known values

% increase = 15 ÷ 14 × 100

Divide

% increase = 1.07 × 100

Multiply

% increase = 107%

The percentage increase is 107%

Hope this helps :)

Company A: 120 + 0.50x

Company B: 60 + 0.60x

Company A = Company B (solve for x)

(Here, x = miles)


120 + 0.50x = 60 + 0.60x

120 - 60 = 0.60x - 0.50x

60 = 0.10x

600 = x
