Answer:
16 years
Step-by-step explanation:
Given data
For the first tree
let the expression for the height be
y=4+x--------------1
where y= the total height
4= the initial height
x= the number of years
For the second tree, the expression is
y=12+0.5x-------------2
Equate 1 and 2
4+x=12+0.5x
x-0.5x=12-4
0.5x= 8
x= 8/0.5
x=16
Hence it will take 16 years for both trees to have the same height
Answer:
He has saved $140.
Step-by-step explanation:
Since 35% translates to 0.35, 35% of 400 is (0.35)(400) = 140
FIND SALE PRICE
= $230 - ($230*20%)
= $230 - $46
= $184
OR
= $230 * (100%-20%)
= $230 * 80%
= $184
*use the method you're most comfortable with or that your teachers prefer
FIND TOTAL WITH TAX
= $184 + ($184 * 11.5%)
= $184 + $21.16
= $205.16
ANSWER: The shoes with discount and taxes cost $205.16.
Hope this helps! :)
Answer:
The percent change in quantity is -0.14%.
Step-by-step explanation:
The formula to compute the change in quantity is:
The income elasticity of demand is 2.80.
Percent change in price is -5% (since the prices decreases)
Compute the percent change in quantity demanded as follows:
Thus, the percent change in quantity is -0.14%.
