The value decreases by 40,000 per year (500000-42000/2 years) the value will decrease by 240000 in six (4 years plus 2 years already passed) years. 6 x 40,000 =240000

So, the value should be 260,000 (500000-240000)

year 1 500000-40000=460000

year 2 460000-40000=420000

year 3 420000-40000=380000

year 4 380000-40000=340000

year 5 340000-40000=300000

year 6 300000-40000=260000

Students sold 300 tickets for a playoff game in basketball at school. Some tickets are for students and cost $4.00, while the re

Neko [114]

So baically

reresent
s=number of studne tickes bouthgt
a=number of adult tickets bought

300 tickest sold
total=300
a+s=300

value=rate times number of peple

student value=4s
adults value=10a
total value=1950
4s+10a=1950

a. system of equations are
s+a=300
4s+10a=1950

b. solve

s+a=300
4s+10a=1950

a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution

4s+10a=1950
<u>-4s-4a=-1200 + </u>
0s+6a=750

6a=750
divide 6
a=125

subsiute
s+a=300
s+125=300
subtract 125
s=175

a. s+a=300
4s+10a=1950

b. solution above
175 students
125 aduls
