A high school drama club is selling tickets for the spring production. One day the president sold 12 adult tickets and 5 child tickets for a total of $169. The next day the president sold 22 adult tickets and 10 child tickets for a total of $314. Let
a represent the cost of one adult ticket. Let c represent the cost of one child ticket. Which system of equations will solve
for a and c?
12a+50=314
22a+10C = 169
0 120+50= 169
22a+100=314
5a+12C= 314
22a+100= 169
o 22a+50= 169
12a+100=314

step-by-step explanation:

no

step-by-step explanation:

d. you cannot tell because there are no values shown.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
