Answer:
$180
Step-by-step explanation:
To find the new cost, multiply the original cost by 1.2
150(1.2)
= 180
So, the new cost of the bicycle is $180
37.5% of 32 is 12
if you move the decimal point in the percentage 2 places to the left you will get a number you can multiply with
so 0.375 x 32 = 12
This is an exponential decay problem.
Using the equation Y = a *(1-rate)^time
where Y is the future value given as 12,000 and a is the starting value given as 13,000.
The rate is also given as 5%.
The equation becomes:
12,000 = 13,000(1-0.05)^x
12,000 = 13,000(0.95)^x
Divide each side by 13000:
12000/13000 = 0.95^x/13000
12/13 = 0.95^x
Use the natural log function:
x = ln(12/13) / ln(0.95)
x = 1.56 years. ( this will equal 12,000
Round to 2 years it will be less than 12000.

Answer: 4x-3x, and 8y+2y. x+10y is the equation in simplest form.
Step-by-step explanation:
Step 1. You need to combine like terms:
4x-3x, and 8y+2y. x+10y would make the equation( 4x + 8y - 3x + 2y) in simplified form.
Hope I could help! :)
