The price of a math book after a discount of 25% is $36. What is the original price of the math book?

1 answer:

3 0

If $36=75%,
That means we can divide both sides by three to get $12=25%,
And because 25x4 is 100, we multiply both sides of the equation by 4 to get $48=100%,
So the answer is $48 dollars.

This also worked for me but I’m not sure it’s the most reliable way:
36 ÷ 0.75 = 48
(amount after discount ÷ percentage that is remaining)

Nastasia [14]

Answer:

Pam (6 years), Tia(8 years), Veronica(11 years) , Lily (15 years)

Step-by-step explanation:

Age of Tia = 8 years

______________________________________________

Given Tia is 2 years older than Pam

mathematically

age of Pam + 2 years = age of Tia

age of Pam + 2 years = 8 years

age of Pam = 8 years- 2 years = 6 years

______________________________________________

Given Pam is five years younger than Veronica

we can infer that age of veronica is age of Pam + 5 more years

mathematically

age of Pam + 5 years = age of Veronica

6 years + 5 years = age of Veronica

age of Veronica = 11 years

______________________________________________

Given Veronica is four years younger than Lily

we can infer that age of Veronica is (age of Lily - 4 years)

mathematically

age of Veronica = age of lily - 4 years

11 years = age of lily - 4 years

age of lily = 11 years + 4 years = 15 years

age of lily = 15 years

______________________________________________

Arranging the list from youngest to oldest we have

age of Pam = 6 years

Age of Tia = 8 years

age of Veronica = 11 years

age of lily = 15 years

Arranging sisters in order of youngest to oldest

Pam, Tia, Veronica , Lily

Joanne has a goal of buying a townhome and saved for 5 years. She expected to have the down payment of $15,000 saved by now but

serg [7]

Answer:

Step-by-step explanation:

Average amount saved per year = $\frac{15,000}{5}$

=$ $3000$

So on average Joanne has saved $3000 per year. She only needs $2000 more which will not even take a year to save.

How many months it will take to save $2000:

$\frac{12}{3000} \times2000$

= $8$ Months.

It will only take Joanne 8 moths to save $2000.

If she really wants to buy the home now she can always go for a home loan scheme for $2000. Any interest rate less than 50% per year is fine as she can save $3000 per year.
