Budget = $130,000 | Number of people to be hired = 34

Hours per week = 40 hours | Weeks to be worked = 8 weeks

Total hours to be worked in the program per person = Weeks * Hours per week = 40 hours * 8 weeks = 320 hours

Hourly rate for 18 of the people = $10 per hour

Cost for 18 of the people = Number of people * Hourly rate * Total hours per person = 18 * 10 * 320 = $57,600

Hourly rate for 13 of the people = $9 per hour

Cost for 13 of the people = Number of people * Hourly rate * Total hours per person = 13 * 9 * 320 = $37,440

Hourly rate for 3 of the people = $15 per hour

Cost for 3 of the people = Number of people * Hourly rate * Total hours per person = 3 * 15 * 320 = $14,400

Since taxes will be paid by hired people themselves, therefore, we will not consider taxes.

Total Amount to be paid to 34 hired people = Cost for 18 of the people + Cost for 13 of the people + Cost for 3 of the people

Total Amount to be paid to 34 hired people = $57,600 + $37,440 + $14,400

Total Amount to be paid to 34 hired people = $109,440

Since Budget is $130,000 and Amount to be paid to 34 people is $109,440, you are below Budget by $20,560.
