Answer:
c and
28.57%
Step-by-step explanation:
count how many number fall into each category
50-59 has 1
60-69 has 2
70-79 has 4
80-89 has 4
and 90-99 has 3

to find the % of those that are between 70-79, take the total number of items that fit into that category (4) and divide by the total number of items (14)
4/14=.2857 --> turn to a percent .2857*100= 28.57%
