Question 179264
Let {{{c}}}= price of a senior citizen ticket
Let {{{s}}}= the price of a student ticket
given:
(1) {{{4c + 5s = 102}}}
(2) {{{7c + 5s = 126}}}
Subtract (1) from (2)
{{{3c = 24}}}
{{{c = 8}}}
And, from (1)
(1) {{{4c + 5s = 102}}}
{{{4*8 + 5s = 102}}}
{{{5s = 70}}}
{{{s = 14}}}
One senior ticket was $8 and one student ticket
was $14
check:
(2) {{{7c + 5s = 126}}}
{{{7*8 + 5*14 = 126}}}
{{{56 + 70 = 126}}}
{{{126 = 126}}}
OK
