Azoo train ride costs $6 per adult and $1 per child. on a certain day, the total number of adults (a) and children (c) who took the ride was 35, and the total money collected was $70.
what was the number of children and the number of adults who took the train ride that day, and which pair of equations can be solved to find the numbers?

a. 7 children and 28 adults
equation 1: a + c = 35
equation 2: 6a – c = 70

b. 7 children and 28 adults
equation 1: a + c = 35
equation 2: 6a + c = 70

c. 28 children and 7 adults
equation 1: a + c = 35
equation 2: 6a + c = 70

d. 28 children and 7 adults
equation 1: a + c = 35
equation 2: 6a – c = 70

you if you answer! c?

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
