Please help Kenya bought 4 boxes of
pencils for $3.99 each. She
also bought 2 boxes of
markers for $4.99 each. If
she paid the cashier with a
$50 bill, how much change
will Kenya get back?

$24.06

Step-by-step explanation:

pencils: x

markers = m

y = total

y - (4x + 2m)

50 - (4*3.99 + 2*4.99)

50 - (15.96 + 9.98)

50 - 25.94

24.06

24.94

Step-by-step explanation:

4 times 3.99 is 15.96

2 times 4.99 is 9.98

15.96 plus 9.98

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

"a" determine whether sage found the correct quotient. show your work
