Answer:
The number of single-shot espressos sold by the cafe was 49.
Step-by-step explanation:
It is provided that Addison's Cafe offers two kinds of espresso: single-shot and double-shot.
Total number of espressos sold by the cafe yesterday afternoon was,
<em>N</em> = 70
The proportion of single-shot espresso sold was, <em>p</em> = 0.70.
Let <em>X</em> = number of single-shot espressos sold.
Compute the number of single-shot espressos sold by the cafe as follows:


Thus, the number of single-shot espressos sold by the cafe was 49.
This is a geometric sequence of the form:
a(n)=ar^(n-1) in this case a=150, r=1.1
a(n)=150(1.1)^(n-1) August is the eighth month so
a(8)=150(1.1)^7
a(8)=292.307565
So you deposited $292.31 (to the nearest cent) in August.
