X + y = 152, 8.5x + 12y = 1,656 How many hats were sold?

Elodia [21]

Answer:

x = 48 and y = 104

Step-by-step explanation:

Given equations are:

$x+y = 152\\8.5x+12y=1656$

From equation 1:

$x = 152-y$

Putting the value of y in equation 2

$8.5(152-y)+12y = 1656\\1292-8.5y+12y = 1656\\3.5y+1292 = 1656\\3.5y = 1656-1292\\3.5y = 364\\\frac{3.5y}{3.5} = \frac{364}{3.5}\\y = 104$

Now we have to put the value of y in one of the equation to find the value of x

Putting y = 104 in the first equation

$x+y = 152\\x+ 104 = 152\\x = 152-104\\x = 48$

Hence,

The solution of the system of equations is x = 48 and y = 104

The value of variable which was assumed for number of hats, is the total number of hats.

Find the simple interest paid to the nearest cent for each principal, interest rate, and time. $570,2%, 4 years.

WARRIOR [948]

The answer is 45.6. You multiply the beginning amount to the interest rate to understand how much interest you get. Then multiply that by the amount of years the interest is gathered. 570 * .02 = 11.4 * 4 = $45.6 interest. Add this to 570 for the original amount of 615.6.
