11. You have one coupon for 15% off on one pound of pork chops. They cost $7 per
pound. How much will 3 pounds cost?

$19.95

Step-by-step explanation:

The total cost for 3 pounds can be found using:

1 pound + 1 pound + 1 pound

We know that there is a coupon for 15% off one pound. Normally you pay for 100%, but since there is 15% off (subtracted), you only pay 85%. (100%-15%=85%)

Multiply 85% and $7.

85%* $7

Convert 85% to a decimal by dividing 85 by 100.

85/100= 0.85

0.85 * $7

Multiply

$5.95

Now we know that 1 discounted pound costs $5.85. The other 2 pounds are regularly priced at $7 each.

1 pound + 1 pound + 1 discounted pound

$7 + $7 + $5.95

$14 + $5.95

$19.95

3 pounds will cost $19.95

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
