Answer:

$8.25

Step-by-step explanation:

discount = x

original price = $45.00

discount% = 15%

x/45 = 15/100

x · 100 = 15 · 45

100x = 675

100x/100 = 675/100

x = 6.75

Sale price = 15 - 6.75 = 8.25

baherus [9]
They bowled for 3 hours and spent $7.

Let x = number of hours
Tucker: 2x+1
Blanca: x+4

2x+1 = x+4
x=3

For the graphs your lines should have equations like this:
y= 2x+1
y=x+4

The point of intersection of these lines should be at point (3,7)

Answer:

  1. A = 1.5
  2. B = -1/3
  3. C = -4/3

Step-by-step explanation:

For A:

  1. A is smack in the middle of 1 and 2, so it it 1 1/2 or 1.5 (same thing)

For B:

  1. Each tick mark between the numbers represents 1/3
  2. B is on the first tick mark between 0 and -1, so therefore it is -1/3

For C:

  1. C is on the first tick mark between -1 and -2
  2. That means C is -1 1/3
  3. -1 1/3 = -4/3

I hope this helps!
