Answer:= 261.905% increase
Solution:
Calculate percentage change
from V1 = 21 to V2 = 76
(V2−V1)|V1|×100
(V2−V1)|V1|×100
=(76−21)|21|×100
=(76−21)|21|×100
=5521×100
=5521×100
=2.61905×100
=2.61905×100
=261.905%change
=261.905%change
=261.905%increase
Answer:
Number of days = 3
Step-by-step explanation:
Let
x = number of days
Rebound game rental = 4 + 2x
Girl right game center = 1 + 3x
Equate both rental companies to find x
Rebound game rental = Girl right game center
4 + 2x = 1 + 3x
Collect like terms
4 - 1 = 3x - 2x
3 = x
x = 3 days
Number of days = 3

Should be the right answer
Ratio 1:2:3 means we have x, 2x and 3x as the three parts
x+2x+3x = 42
6x = 42
6x/6 = 42/6
x = 7
Since x = 7, this means 2x = 2*7 = 14 and 3x = 3*7 = 21
Dividing 42 into the ratio of 1:2:3 means we have 7:14:21 as the answer
If we divide all three parts of 7:14:21 by the GCF 7, we reduce it down to 1:2:3
As a check,
7+14+21 = 21+21 = 42
so it works out
