The answer will be A because 3x=-3
X= -1
Given that the depth varies directly with amount of rainfall, then we shall have:
let d be the depth and r be the rainfall amount
dαr
thus
d=kr
where, k is the constant of proportionality, thus the formula will be:
d=kr
The answer is x<0 and y<0
Turn that percent into a decimal and multiply that by $7.50. 0.04(7.50)=.30. Add that to the original value. 7.50+.30=7.80. It will be $7.80 after a 4% sales tax.
