Sveta_85 [38]

Answer: $5,895

Step-by-step explanation:

First you want to add the earnings in order to find the total value being taxed.

17,500 + 15,250 = 32,750

We can then find the percent as a decimal by dividing it by 100:

$\frac{18}{100} = .18$

We can then multiply the total earnings by this decimal to find the total income tax:

$32,750 * .18 = 5,895$

Assume that y varies inversely with x. If y=7 when x=2/3, find y when x=7/3

fgiga [73]

Inverse variation is of the form:

y=k/x, which we can express as:

yx=k we are given the point (2/3, 7) so we can solve for k

7(2/3)=k

14/3=k

y=14/(3x), so when x=7/3

y=(14/3)/(7/3)

y=(14/3)(3/7)

y=2
