Answer:

$4.081

Step-by-step explanation:

We have been given that Melissa owns a credit card with a 8.9% APR. The balance after her last billing cycle was $550.

First of all, we will find period rate by dividing APR by 12 as 1 years equals 12 months.

$\text{Period rate}=\frac{8.9\%}{12}=0.74166\%$

The finance charge would be 0.74166% of $550.

$\text{The finance charge}=\$550\times \frac{0.742}{100}$

$\text{The finance charge}=\$550\times 0.00742$

$\text{The finance charge}=\$4.081$

Therefore, the finance charge would be $4.081.

Mashutka [201]

Let's use the variable "r" to represent the investment rate of the stocks:
2r(500) + r(800) = 45
1000r + 800r = 45
1800r = 45
r = 0.025
2r = 0.05
The $500 is invested at 5%

butter and flour are mixed in the ratio 2:3. paul has 640 grams of butter and 880 grams of flour. how much more flour does he ne

madam [21]

Answer:

80g

Step-by-step explanation:

Here's why:

SO you have 2:3 ratio which means the ratio for grams of butter/grams of flour has to be 2:3.

So we set up the following equation:

2/3 = 640/x (solve for x)

x= 960g

960g is what you should have to get to ratio, but the question is asking how much more you need from the initial given flour.

So you need (suppose x is the grams of flour you need)

x+880g = 960g (solve for x)

x=80g
