9/10. make the bottom numbers the same to add fractions. you can do that by multiplying 7/10 by 10/10.

70/100 + 20/100 = 90/100

90/100 = 9/10

you can also reduce 20/100 to 2/10.

7/10 + 2/10 = 9/10

Answer:

Option a. $300

Step-by-step explanation:

Let

x ----> the cost of the rent monthly per person

we know that

The number of persons is 3 (Sal and two friends)

The cost of the security deposit per person is equal to

$\$1,200/3=\$400$

If Sal paid a total of $1,000 to move in

then

That means that the cost per person of two months of rent (first and last month) plus $400 (security deposit per person) must be equal to $1,000

$2x+400=1,000$

solve for x

$2x=1,000-400\\2x=600\\x=\$300$

Travis has a savings account that his parents opened for him. It pays 6% annual interest. His uncle also opened an account for h

mezya [45]

So let's say the amounts are "a" and "b", at 6% and 8% respectively.

how much is 6% of a? well (6/100) * a, or 0.06a.
how much is 8% of b? well (8/100) * b, or 0.08b.

so hmm whatever "a" and "b" amounts are, we know that their yield is $100, thus 0.06a + 0.08b = 100.

now, there's more money in "a" than in "b", 500 bucks more, so whatever "b" is, we know that a = b + 500.

$\bf \begin{cases}
0.06a+0.08b=100\\
\boxed{a}=b+500\\
----------\\
0.06\left( \boxed{b+500} \right)+0.08b=100
\end{cases}
\\\\\\
0.06b+0.08b+30=100\implies 0.02b=70\implies b=\cfrac{70}{0.02}
\\\\\\
b=3500$

how much was deposited in the 6% one? well, a = b + 500.
