You would have to transform the fractions to decimals by dividing. For the first one, if you divide 4 by 5 you get .8. To transform a decimal to percent you move the decimal place 2 times to the right or multiply by 100 (They both would give you the same thing)

The formula P=nc-e gives the profit p when a number of items n are each sold at a cost c and expenses e are subtracted. If p=570
m_a_m_a [10]


1.65

You can substitute in the values of p, n and e to get the equation:
5700 = 4000c - 900

add 900 to both sides and you get

6600 = 4000c

divide both sides by 4000 and you get

1.65 = c

so the answer is 1.65

x --> Arm span

y --> Foot span

The linear relationship is formed with the armspan.
