5.2 + 6.75 = 11.95
A) control group, they did not also survey 10 other ppl who took a placebo
In the given question,the given explicit formula is
Which is of the form
So the constant difference is 7 here.
Now for the recursive formula
To find the next term, we need to add 7 to the current term, that is
So the correct option is B
Answer:
$189
Step-by-step explanation:
Let their total amount of spending money be x
given that $135 they spent is 5/7 of their total spending money,
mathematically:
135 = (5/7) x (multiply both sides by 7)
135 (7) = 5x
945 = 5x
5x = 945 (divide both sides by 5)
x = 945 / 5
x = 189
