Heather has been offered two options for her salary as a trainer at the gym option a would pay her$25000 plus $15 for each training session. Option b would pay her $10000 plus 40$ for each training session how many training sessions would make the same salary options equal solve using substitution

Sagot :

Answer:

It would take 600 training sessions to make the two salary options equal

Step-by-step explanation:

Let x be the number of sessions

25000 + 15x = 10000 + 40x

Transpose

25000 - 10000 = 40x - 15x

15000 = 25x

Divide both sides by 25

600 = x

x = 600

Check:

25000 + 15(600) = 10000 + 40(600)

25000 + 9000 = 10000 + 24000

34000 = 34000 ✓
