<span><span>1.
</span>A department store has a discount on shoes based
on percentage of price.
=> one pair of shoes marked down from 70 dollars to 49 dollars
=> let’s solve for the percentage rate.
=> 70 – 49 = 21, the than ½ of the price
=> 70 x 30% = 21
Thus, the percentage rate is 30%
For the pair of shoes that is 110 dollars
=> 110 * .30 = 33
=> 110 – 33 = 77
Thus, the price of pair of shoes is now 77 dollars.</span>
It is "D" because the equation is 2*3.14*25=157m
Hope That helps!
