Ben is making costumes for the school play. For each costume he needs 2.125 yards of fabric. Fabric is $3.49 a yard and sales tax is 6%. Calculate the cost to make 13 costumes

$7.87

Step-by-step explanation:

Step one:

given data

For each costume, he needs 2.125 yards of fabric

cost of Fabric is $3.49 a yard

Required

The total cost of making the costume

Step two:

Hence the total cost of fabric needed is = 2.125*3.49= $7.42

sales tax is 6%

= 6/100*7.42

= 0.06*7.42

=$0.45

Therefore total cost of the costume is = 7.42+0.45= $7.87

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
