Need help with two word problems

dangina [55]

Answer:

E. 18 children are buying their lunches

F. Rock must pay $50 each month

Step-by-step explanation:

To find a percentage you multiply the number by the percentage;

60 x 70%(0.70) = 42 children brought their lunches

But we need the amount buying their lunches so we would subtract 60 by 42;

60 - 42 = 18 buying their lunches

Again, to find the percentage we multiply it by the original;

$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa

Now we need to find how much Rock still needs to pay for the sofa;

$800 - $200 = $600 more needed to pay for the sofa

Lastly, we must find how much Rock will need to pay each month to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;

$600 / 12 = $50 needs to be paid each month for a year

Ciara Larry and jeeta pick apples at an orchard Ciara pick twice as many pounds is Larry and three times as many pounds as jeeta

steposvetlana [31]

Answer:

The pounds of apples picked by Ciara was 4,560

The pounds of apples picked by Larry was 2,280

The pounds of apples picked by Jeeta was 1,520

Step-by-step explanation:

Let

x -----> pounds of apples picked by Ciara

y ----> pounds of apples picked by Larry

z ----> pounds of apples picked by Jeeta

we know that

$x+y+z=8,360$ ----> equation A

$x=2y$

$y=x/2$ ----> equation B

$x=3z$

$z=x/3$ ----> equation C

substitute equation B and equation C in equation A and solve for x

$x+x/2+x/3=8,360$

Multiply by 6 both sides to remove the fractions

$6x+3x+2x=50,160$

$11x=50,160$

$x=4,560\ lb$

Find the value of y

$y=x/2$ ----> $y=4,560/2=2,280/ lb$

Find the value of z

$z=x/3$ ---> $z=4,560/3=1,520\ lb$

therefore

The pounds of apples picked by Ciara was 4,560

The pounds of apples picked by Larry was 2,280

The pounds of apples picked by Jeeta was 1,520

A function follows the rule y = -75 - 5x. When the function's output is 25, the equation is 25 = -75 - 5x. What is the function

svetlana [45]

Answer:

The function input is -20 when the output is 25

Step-by-step explanation:

we have

$y=-75-5x$

where

y is the dependent variable or output

x is the independent variable or input

If the output is 25

then

y=25

substitute

$25=-75-5x$

Solve for the function input is the same that solve for x

Isolate the variable x

Adds 5x both sides

$25+5x=-75-5x+5x$

$25+5x=-75$

subtract 25 both sides

$25+5x-25=-75-25$

$5x=-100$

Divide by 5 both sides

$x=-20$

therefore

The function input is -20 when the output is 25
