Tamara earns 2,050 every month. She spends 65% on the amount that she earns. The rest of the money is equally divided and deposi

victus00 [196]

Answer:

Tamara earns $2,050 each month.

She spends 65% of that, so the amount that she spends is:

S = (65%/100%)*$2,050 = 0.65*$2,050 = $1,332.50

Then the amount that she has left is:

R = $2,050 - $1,332.50 = $717.50

Now she divides that in half, and deposits those amounts in two separate accounts.

She deposits $717.50/2 = $358.75 in each acount.

Then she deposits $358.75 per month, so after x months she has:

x*$358.75 in each of those accounts, so one of the accounts will have more than $2,500 when:

x*$358.75 = $2,500

x = $2,500/$358.75 = 6.96

So after 6.96 moths she will have more than $2,500 in one of her accounts, we can round it to:

After 10 months Tamara has deposited more than 2,500 in one of her accounts.

What is -7 2/3 + (-5 1/2) + 8 3/4

Veseljchak [2.6K]

Hey there :)

$-7 \frac{2}{3} = - \frac{23}{3}$
$-5 \frac{1}{2} = -\frac{11}{2}$
$8 \frac{3}{4} = \frac{35}{4}$

$- \frac{23}{3} - \frac{11}{2} + \frac{35}{4}$

We need to change all fractions to have a common denominator

Lets see:
Multiples of 2: 2 , 4 , 6 , 8 , 10 , 12
Multiplies of 3: 3 , 6 , 9 , 12
Multiplies of 4: 4 , 8, 12

The common denominator is 12
2 x 6 = 12
3 x 4 = 12
4 x 3 = 12

= $-\frac{23(4)}{3(4)} - \frac{11(6)}{2(6)} + \frac{35(3)}{4(3)}$
= $- \frac{92}{12} - \frac{66}{12} + \frac{105}{12}$

We need to add the numerators while keeping the same denominator
= $- \frac{53}{12}$
= $-4 \frac{5}{12}$
