Aperson on tour has dollar 360 for his daily expenses. if he extends his tour for 4 days, he has to cut down his daily expenses by dollar 3. find the original duration of the tour. (hint use quadratic equation)

The original duration of the tour  is 18 days.

Step-by-step explanation:

Let

the number of days spent be T

Daily expenses be D

Initially ,

total tour expenses was 360

-------------(1)

If he extends his tour for 4 days, he has to cut down his daily expenses by dollar 3

---------------(2)

Expanding the eqaution(2)

DT-3D + 4T -12 = 360

Substituting the value of D

Solving the quadratic equation we get

T = 18  and T = -15

T is the number of gays and it cannot be negative , hence T is 18

Substituting in equation (1) we get

D =  20

do you mean add both of the equations together

because if you do the answer is 10x-5
