1 answer:
marysya [2.9K]3 years ago
5 0

Answer:

40

Step-by-step explanation:

if you used cross products you'd pair 8 with 100 and n with 20

That written out would be 8(100)=20n

8(100)=800

800=20n

Divide on both sides

800/20=40

20/20 (cancels out)

Therefore n=40

A jar of peanut butter and a jar of jam cost $10.20 in total. the jar of peanut butter costs $10.00 more than the jar of jam. ho
Olegator [25]
Well this is pretty simple. So the first thought is that the peanut butter would be 10$ and the jam would be 0.20$, however, the peanut butter would not be 10$ more. Instead, subtract the 10$ from the total, which gives you 0.20$, and then divide that by two. Now you have 0.10$ for each, along with another 10$ for the peanut butter. The peanut butter would be $10.10, and the jam would be 0.10$ (that's pretty cheap!).

ikadub [295]

Step-by-step explanation:

line up $ and % data like this:

$2.79 represents 100%

$3.79 represents  X%

cross multiply

X*2.79 = 3.79*100

divide both sides by 2.79

X= 3.79*100 / 2.79 ≈ 136%

so it increased 36%
