If there are 300 students in the Spanish Club in the county predict how many are 10th graders.

140 students are probably 10th graders

Step-by-step explanation:

This survey is supposed to represent the whole of the group, and so it is reasonable to assume that the ratios and percentages of people in each grade would be equal in the same as it is in the whole. For this sample, we have a total of 30 people surveyed (14+8+5+3), and 14 of them are 10th graders. Then, you would set up a proportion to find the number of 10th graders in 300. The equation would be 14/30=x/300. This isnt very hard to figure out because you just cross multiply to get 30x=4200, and you then divide each side by 30 to isolate x, which leaves you with x=140. This leaves you with the answer that 140 students are 10th graders.
