Answer:
y = 8.5
Step-by-step explanation:
PART A
write two different, equivalent expressions for how much the rosebush will cost if the coupon is applied first and the 10% discount second. <em><u>d-(d-5)</u></em><em><u>.</u></em><em><u>10</u></em><em> </em>= 27.5 <em>(if you put d in as 30!)</em>
PART B
write an expression for how much the rosebush will cost if the 10% discount is applied first and the coupon is applied second. <em><u>d-(d*.10)-5</u></em><em> </em><em> </em>=22 <em>(if you put d in as 30!)</em>
PART C
which order will save marina more money? explain your reasoning.
<u>d-(d*.10)-5</u><u> </u>This equals less! if you put in 30 as an example
So, A) <u>d-(d-5).10 </u>B)<u> </u><u>d-(d*.10)-5</u><u> </u>C) <u>d-(d*.10)-5</u>
Answer:
The number of fishes person b initially has is 0
The number of fishes person a initially has is x, where x is any natural number
Step-by-step explanation:
The given parameters are;
let x represent the number of fish person a catches and let y represent the number of fishes that person b catches, we have;
x - x/2 = y + x/2
2·x - x = 2·y + x
2·x = 2·y + 2·x
∴ y = 0
Therefore;
The number of fishes person b initially has = 0
The number of fishes person a initially has = x, where x is any natural number.
