Answer:
he used 1/4 yards per skhirt
Answer:
B
Step-by-step explanation:
100% is unknown 100:20 is 5
8,000*5=40,00
-3x-12> 8x + 21
+12 +12
-3x > 8x + 33
-8x -8x
-11x > 33
————-
-11
x < -3
I moved the real numbers to one side and and the variable to the other side to solve for the inequality
I also remembered somewhere that if you divide by a negative number the inequality sign switches.
Answer:

Step-by-step explanation:
Given

Required
Graph the solution

Multiply both sides by 3



<em>See attachment for graph (Assume T is on the x-axis)</em>
2.5 % = 2.5/100 = 0.025
Multiply $80k by 0.025, so$2000 if my mental math serves correctly
