Hey You!

Let's solve this step-by-step:

9.99 * 20% = 1.998

9.99 - 1.998 = 7.992

7.992 * 6.75% = 0.53946

7.992 + 0.53946 = 8.53746

The total cost of his order is $8.53

A quantity, y, varies directly as x When y=10, x=6.<br> Find xwhen y= 14.
grigory [225]

The value of x when y = 14 is 8.4

<h3 />

<h3>How to solve variation ?</h3>

y, varies directly as x. Therefore,

y ∝ x

Therefore,

y = kx

where

  • k =constant of proportionality

Therefore,

10 = 6k

k = 10 / 6

k = 5 / 3

Hence, when y = 14

y = kx

14 = 5 / 3 x

cross multiply

42 = 5x

x = 42 / 5

x = 8.4
