Answer:

Doug sold 100 sandwiches in his neighborhood.

Step-by-step explanation:

To solve for percentage you have to first find the percentage's decimal. To find this you have to the move the decimal point up to places. This makes 80 into 0.8. After you do this you will mutiply that but the total amount. So 125 times 0.8. Once you do this you should get 100. This means that Doug sold 100 sandwiches in his neighborhood.

The slope of the equation would be 7/3 since the original slope was -3/7. We already know y int (b) so the eqn is

y = 7/3x + 2

Luther opened a savings account and deposited $400.00. The account earns 4% interest,compounded annually. If he wants to use the

Tcecarenko [31]

To solve this problem, we must use the formula:

$A=P\cdot(1+\frac{r}{n})^{t\cdot n}\text{.}$

Where:

• A = final amount = ?,

• P = starting amount = $400.00,

• r = interest rate in decimals = 4% = 0.04,

• n = number of times per year that the interest is compounded = 1 (because interest is compounded annually),

• t = time in years = 2.

Replacing the data of the problem in the equation above, we get:

$A=400.00\cdot(1+0.04)^2=432.64.$

Answer

After 2 years, he will be able to spend $432.64 on the bike.
