A) 150% is also 1 1/2 times the original amount, so to find 100% of the number divide it by 3 to get 21 for the bike and 7 for the helmet, then multiply it by 2.
The bike cost $42 and the helmet cost $14 for the company.
B) They earned $21 for the bike and $7 for the helmet, the numbers we got earlier by dividing the other numbers by 3, which is how much they marked up prices.
Hope this helps!

Wait so 20/2? -2?? Sorry i’m not sure!
Answer:
Step-by-step explanation:
The slope of a line is defined as m=(y2-y1)/(x2-x1) we are told the slope m is -1/7 and we are given points (-21, 1/2) and (-7, y) so we can say
(.5-y)/(-21- -7)=-1/7
(.5-y)/(-14)=-1/7
.5-y=2
-y=4
y=-4
