Answer:
Expression: Y = -10/3 X
Y = 10/3
Step-by-step explanation:
If Y varies directly as X, then;
Y∝X
Y = kX
k is the constant of variation
If Y = 10 and X = -3
10 = -3k
k = -10/3
Substitute k = -10/3 into the expression Y = kX
Y = -10/3 X
This gives the required expression
To get the value of Y when X = -1
Recall that Y = kX
Y = -10/3 (-1)
Y = 10/3
Hence the value of Y is 10/3

$14.8 was the markup, And the price went up in 22%, how I got my answer!
I first found that adding $64+$14.8=$78.8, and for percentage, that took awhile. At first I thought that it would be 20% but upon further investigation I found that, 22% Of $64 is $14.8.
I hope this helps!
P.S. 20% of $64 is $12.8.
