Answer:

$22.58

Step-by-step explanation:

100% of $10 is another $10, so that is already $20. 15% of 100 is $1.50, so you get $21.50. The overall sales tac the 5% is for the entire product, and 5% of the total would be 1.075, which you add to $21.50 which gets you to 22.575, which rounds to 22.58

Answer:

3.5 miles

Step-by-step explanation:

The straight line distance from the school to the mall is found using the Pythagorean theorem. That distance is the hypotenuse of a triangle that is 27 blocks in the east-west direction and 22 blocks in the north-south direction.

d = √(27^2 +22^2) = √1213 ≈ 34.83 . . . blocks

Since each block is 0.1 miles, the distance in miles is ...

distance to mall = (0.1 miles/block)(34.83 blocks) = 3.483 miles

Rounded to tenths, the distance from school to mall is 3.5 miles.
