To find 40% of 75 and calculate 2 of 5 . 75 . Does her calculation Correct value for 40% of 75

pickupchik [31]

Answer:

Yes, her calculation is correct. The value of 40% of 75 is 30.

Step-by-step explanation:

The value of 40% of 75 is

$\frac{40}{100}\times 75=\frac{3000}{100}=30$

The value of $\frac{2}{5}$ of 75 is

$\frac{2}{5}\times 75=2\times 15=30$

From the above calculation it is noticed that the value of 40% of 75 and $\frac{2}{5}$ of 75 are same, therefore the calculation is correct and the value of 40% of 75 is 30.

Heather makes $6.50 per hour. Every three months, she is eligible for a 2% raise. How much will she make after 2 years if she ge

sammy [17]

Answer:

$7.62 per hour

Step-by-step explanation:

Since, Heather gets a raise every 3 months, in 2 years, she will get a raise 8 times (2years = 24 months, 24 divided by 3 is 8).

Now it becomes a compound growth problem. We can use the formula shown below to solve these type of problems.

$F=P(1+r)^t$

Where,

F is the future value (what we want to find)
P is the present rate ($6.5)
r is the rate of growth, in decimal (2% growth means 0.02)
t is the time frame, number of times compounding occurs (for our case we have figured it to be 8)

Now plugging in all the info, we get the value of F:

$F=P(1+r)^t\\F=6.5(1+0.02)^8\\F=6.5(1.02)^8\\F=7.62$
