Answer:
d. May
Step-by-step explanation:
Working through the chain, we have ...
Feb = 1.10×Jan
Mar = 0.85×Feb = 0.935×Jan
Apr = 1.20×Mar = 1.122×Jan
May = 0.90×Apr = 1.0098×Jan
Jun = 1.05×May = 1.06029×Jan
The multiplier that is closest to 1 is 1.0098, so May has sales closest to January.
_____
The percentage increase or decrease can be converted to a multiplier by adding it to 1. If p% is the percentage change, then adding it to an original value looks like ...
original + p% × original = original × (1 +p%) . . . . . . . distributive property
And p% translates to a decimal number by replacing % with /100 or ×0.01.
10% increase: original × (1 + 10/100) = original × 1.10
15% decrease: original × (1 - 15/100) = original × 0.85
Answer:
Then answer is 10.
Step-by-step explanation:
9 would cover 1,800 square feet so 925 square feet would be left so you should buy 10 cans.
Since the skier has to rent skis for 30 dollars per day with
both passes, we can ignore it while solving the question.
A season pass is 350, while a daily pass is 75.
So a seasonal pass is equivalent to having 4.6667 daily passes. And you can't buy 0.6667 of a pass.
So, if you went at least 5 days with a seasonal pass, then the seasonal pass would be less expensive than a daily pass.
Answer:
6x - 1
Step-by-step explanation:
Okay this is basically polynomial algebra:
1. Add the value of the lengths already given.
like terms: 3x + x = 4x, -4 + 2 = -2. Now you're left with, 4x - 2.
2. Find the difference between the perimeter and the sum of the lengths.
(10x -3) + (4x + 2) = 6x - 1
