Margo borrows $500, agreeing to pay it back with 3% annual interest after 14

Akimi4 [234]

Answer:

$\$17.50$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest to pay

P is the amount of money borrowed

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=\frac{14}{12}\ years\\ P=\$500\\r=3\%=3/100=0.03$

substitute in the formula above

$I=500(0.03)(\frac{14}{12})$

$I=\$17.50$

Write two expressions to show a number increased by 11. Then, draw models to prove that both expressions represent the same thin

ioda

Answer:

n + 11 and 11 + n

Step-by-step explanation:

Let n be the unknown number,

n is increased by 11,

That is, n + 11

By the commutative property of addition,

The expression would be,

11 + n

For drawing a model that shows n + 11

Take two boxes in which first shows n and second shows 11 and add them,

Similarly, for showing 11 + n, take first box that shows 11 and second box that shows n then add them.
