218.7 / 6.75 = 32.4 you divide the area by the base
During the sale,
$450 x (100% - 40%)
$450 x 60% = 450 x 0.6 = $270 = answer 1
After the sale,
$270 x 1.4 = $378 = answer 2
3rd place =1000
2nd place =2000
1st place =8000
Total= 11,000
Answer:
-8
Step-by-step explanation:
Solving for r means that we need to isolate r from the expression.

Multiply both sides by (r +6) to 'get rid' of the fraction:
-8= 4(r +6)
Expand:
-8= 4r +4(6)
-8= 4r +24
Minus 24 on both sides:
4r= -8 -24
4r= -32
Divide both sides by 4:
r= -32 ÷4
r= -8
