Joan works on commission for a furniture store. She gets a base pay of $80 a day plus 4 percent of the value of any merchandise

she sells that exceeds a total of $400. Joan wrote the expression 400 + 0.04(t − 80), where t represents her sales total in dollars, to compute the total amount of money that she will make. For sales of $500 Joan calculated that she will make $416.80. Explain Joan's error by completing the correct expression and how much she will make.

Answer:

Total amount earned = $84

Step-by-step explanation:

The correct expression is

Total amount earned = 80 + 4% of (t - 400)

= 80 + 0.04(t - 400)

where,

t = her sales total in dollars

Total amount of money that she will make for sales of $500

Total amount earned = 80 + 0.04(t - 400)

= 80 + 0.04(500 - 400)

= 80 + 0.04(100)

= 80 + 4

= 84

Total amount earned = $84

If f(x) = x^2, which of the following describes the graph of f(x) - 5?
12345 [234]
In any given equation, a positive or negative number that isn't multiplied by a variable is called "b", or "y-intercept." Seeing as y-5 (f(x) is the same as y) isn't an equation, it probably means you need to add 5 to both sides to isolate y.
you end up with y=5, a horizontal line in which every "y" value in every set of points is equal to 5
Ex: (1,5),(2,5),(3,5)...
this means that your parent function of y=0 has a vertical shift upwards of five. hope I could help :)

18. A store sells two different kinds of rulers, plastic and wood. The receipts show that they have sold 35 total rulers today.
kvv77 [185]

Answer:

12 wooden rulers

23 plastic rulers

Step-by-step explanation:

Total rulers sold - 35

Total profit - $82

1 wooden ruler - $3

1 plastic ruler - $2

$3 x 12 = $36

$2 x 23 = $46

$46 + $36 = $82

12 + 23 = 35 rulers

If f(x)= - 4x-4, g(x)= 4x² + 4x + 2, and h(x)= 3x2 – 3, find f(3).
Deffense [45]

Answer:

f(3) = -16

Step-by-step explanation:

Given

f(x)= - 4x-4

g(x)= 4x^2 + 4x + 2

h(x)= 3x^2 - 3

Required

f(3)

We have:

f(x)= - 4x-4

Substitute x = 3

f(3) = -4 * 3 - 4

f(3) = -12 - 4

f(3) = -16

Hence:

f(3) = -16
