Just flip them around: -2 -2 -5 3 8
The equation is given as W varies directly with u and inversely with d, then the equation is written as:
W = k1u
here k2 is the proportionality constant.
and p = k2

here k2 is the proportionality constant.
Thus, combining both equations we get, p = K

where K = K1*K2, is the proportionality constant.

Answer:
$2,400
Step-by-step explanation:
Ken intends to start a savings account
10% = leisure spending
This means 90% = Expenses for school
Let us represent the amount he must save as : x
Hence in other for him to have $2,160 in his savings account, the amount Ken must earn is calculated as:
90/100 × x = $2,160
Cross Multiply
90x = $2,160 × 100
x = ($2,160 × 100) ÷ 90
x =$2,400
Therefore, the amount Ken has to earn to have the amount needed for school is $2,400
