So we know the gym charges $10 to join, and the $4 every visit. He wants to visit 20 times, so we multiply 20 by 4 to get the price of 20 visits, which is $80. Then we add $10 for the joining fee. The total will cost him $90. That means he needs to save $44 to visit 20 times. Hope that helps!
Answer:
the interquartile range is 7
Answer:
x=1/2k
Solution:
4kx+10kx= 7
14kx=7
Divide 14k from both sides.
x=7/14k
x=0.5k
180-109= 171
Angel 8 is 171 degrees
