15 should be greater than (-3w) becuase whatever you times with -3 it'll equal negative something so it's 15.
Write 6% as a decimal : 6% = 0.06
Multiply the price of the shirts by 0.06:
Tax = 24.00 x 0.06 = $1.44
In this question, there is no distributive law...
Distributive law is used when there are brackets:
ex: 2(3y+5z)
= 6y + 10z
If this is in a textbook, then it may be a 'trick' question.
let
i= Interest
p= Principle
r= rate
t= time
data given
i= $2520
p= $7000
t= 4years
r= ?
From the formula
i= prt
we make 'r' the subject by multiplying by pt both sides
i/pt=prt/pt
i/pt=r
its the same like
r=i/pt
r=$2520/($7000×4)
r=$2520/$28000
r=3/350
r=0.09%
therefore the interest rate is 0.09%
