The system of equation that can be used to determine the number of hours Mila worked washing cars last week and the number of hours she worked landscaping last week is

x + y = 14

10x + 11y = 145

Given:

Earnings for washing car = $10

Earnings for landscaping = $11

Total hours worked = 14 hours

Total amount earned = $145

let

number of hours but washing car = x

number of hours landscaping = y

The equation:

x + y = 14

10x + 11y = 145

Therefore, the equation that can be used to determine the number of hours Mila worked washing cars last week and the number of hours she worked landscaping last week is

x + y = 14

x + y = 1410x + 11y = 145
