This question is kinda tricky. LMK if its correct
Answer:
$15.5
Step-by-step explanation:
let a = price of one orchid plant
8 orchids would cost 8 x a = 8a
12 orchids would cost 12 x a = 12a
Let b = price of one lily plant
12 lilies would cost 12 x b = 12b
8 lilies would cost 8 x b = 8b
8a + 12b = 362 -- eqn 1
12a + 8b = 388 -- eqn 2
to solve, multiply equation 1 by 8 and equation 2 by 12
64a + 96b = 2896 equation 3
144a + 96b = 4656 equation 4
substract equation 4 from 3
80a = 1760
a = $22
Substitute for a in eqn 1 and solve for b
8(22) + 12b = 362
b = $15.5
Answer: C.
Step-by-step explanation:
The first number is a positive 4, which is your a1. Then the geometric sequence goes to a negative implying that it is multiplied by a negative. So the a1 = 4 and it is being multiplied by a negative 3.
The answer should be < because 602163 is smaller than 620163
Answer:
You can’t make it the same, but you can make it almost the same.
Maggie would have to rent 4 movies to make the plans’ cost almost the same.
Explanation:
$150-$129= 21
21 divided by 5= 4.2 (You can’t rent 4.2 movies, so we go with 4)
4x5=20+$129= $149 (Almost $150)
So, Maggie would have to rent 4 movies to make the costs almost the same.
Hope this is helpful!!
P.S Sorry if there was another way to make the costs equal, I’m not the best at math!
:D
