<span>First, the formula would be like this dP / dt= KP.
Secondly, since dP is given which is 6.9. Substitute it from the equation.
P(0) = 6.9 x 10^6
integral 1 divided by pdp which will look like this,
integral 1/ PdP = integral kdt
the answer would be .0019 or
k=.0019</span>
To start off, Chang has already saved $45. $125 - $45 = $80. Therefore, he owes $80. $80 ÷ 7 = 11.4285714286, so he needs to work 12 full hours to pay for his trip.
4x/15 = 60/x
4x^2 = 900
x^2 = 225
x = 15
