Question

Sydawna has two part-time jobs. Her earnings for one week are represented by the equation: E = 9.25g + 10.50t

Answer 1

Answer:

• 9 hours

Step-by-step explanation:

Given the equation:

• E = 9.25g + 10.50t

• E - weekly total, g- number of hours at gas station, t- number of hours at toy store.

Substitute given values into equation and solve for the missing one:

• 219.75 = 9.25g + 10.5*13
• 219.75 = 9.25g + 136.5
• 9.25g = 219.75 - 136.5
• 9.25g = 83.25
• g = 83.25/9.25
• g = 9

Sydawna works 9 hours at the gas station
