Sydawna has two part-time jobs. Her earnings for one week are represented by the equation: E = 9.25g + 10.50t
Iteru [2.4K]

Answer:

  • 9 hours

Step-by-step explanation:

<u>Given the equation: </u>

  • E = 9.25g + 10.50t
  • E - weekly total, g- number of hours at gas station, t- number of hours at toy store.

<u>Substitute given values into equation and solve for the missing one:</u>

  • 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
