Answer:
Frida
Step-by-step explanation:
y = 1000(2)^x
Mrs. Smith is saying that the number of termites will double each week, and Mr. Smith is saying that the number of termites will increase by 100% each week.
Let's just look at (2)^x. If we substitute numbers for x, we get:
- x = 1 ⇒ 2
- x = 2 ⇒ 4
- x = 3 ⇒ 8
- x = 4 ⇒ 16
- x = 5 ⇒ 32
- x = 6 ⇒ 64
- x = 7 ⇒ 128
We can see that the output number doubles by 2, or in other words, increases by 100% of its value.
Therefore, Frida is correct in thinking that both Mr. and Mrs. Smith's interpretations are correct.
A primary source saw something first-hand. A secondary source only heard about it.
Answer:
Ed and Sheerie save 7.5%.
Step-by-step explanation:
This question can be solved using a rule of three.
Ed and Sherrie save $90 each pay period from their combined paychecks, which total $1200. What percent do Ed and Sherrie save?
How much of $1200 is $90? $1200 is 100% = 1, $90 = x. So
$1200 - 1
$90 - x
Ed and Sheerie save 7.5%.
