Answer:
The answer is B ...........
The question is asking you to solve for A
to determine the first, fourth and tenth term you simply put those values in for (n)
the first term you then be given by the equation A(1) = 12 + ((1)-1)(3)
A= 12
Same thing for 4th term A(4) = 12 + ((4)-1)(3)
A= 21
10th term: A(10) = 12 + ((10)-1)(3)
A= 39
∴ your answer is C
Sam sold half as many as Odel.
That means Odel sold twice as many as Sam.
Let x = number of pizzas sold by Sam.
Then Odel sold 2x.
Altogether they sold 126
x + 2x = 126
3x = 126
x = 42
Since x is the number of pizzas sold by Sam, that is our answer.
Answer: Sam sold 42 pizzas.
