Answer: 1/2
Explanation:
When y is inversely proportional to x. This implies that:
y = k/x
If y = –8 when x = –2, then the constant of proportionality will be;
y = k/x
-8 = k/-2
k = (-8 × -2)
k = 16
when x = 32, the value of y will be:
y = k/x
y = 16/32
y = 1/2
The value of z is x(.20) = (.40)y
Tax= sales price x tax percent
Tax= $40 x 6.5%
Convert % decimal to decimal: 6.5% by 100
Tax= 40 x 0.065
Tax= $2.60
Answer: sales tax is $2.60
