The options can be rewrited as follow:
A. 5<4
B. 5<5
C. 5<4
D. 4<-5
∴ Answer is none of the above.
Unless perhaps you have written down the question incorrectly.
if Joyce saved $70
at 75% off, Joyce saved 25%
so, $70 is 25%
To find the total price which is 100%, multiply $70 by 4 ( because 25% x 4 = 100% )
so the original price is $70 x 4 = $280
16x - 30 = 12 + 10
6x = 42
x = 7
(-5-c)(-1)
can write as (-1)(-5-c)
multiply(-1) to (-5) then multiply (-1) to(-5)
answer 5+c
