80% of a number is x. what is 40% of the number?

80% of a number is x

so let us say the number is y

that means 80 % of y is x.

Making an equation we have,

So solving for y we have,

Now we have to find what is 40 % of the number.

So we have to find 40 % of y here

0.04 *y = 0.04 (12.5 x)

y=1.5 x

So we can say that 40 % of the number is 1.5 x

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
