Answer:
Each cookbook cost $15.15.
Step-by-step explanation:
Since the statement indicates that four cookbooks and one novel cost $68.75, you can write the following equation:
4x+y=68.75, where:
x is the price of cookbooks
y is the price of novels
Also, given that the novel cost 7 dollars less than a cookbook, you can write the following equation:
x=y+7
Now, you can replace x=y+7 in the first equation:
4(y+7)+y=68.75
4y+28+y=68.75
5y=40.75
y=40.75/5
y=8.15
Now, you can replace the value of y in x=y+7:
x=8.15+7
x=15.15
According to this, the answer is that each cookbook cost $15.15.

The complete sequence solved by arithmetic progression is 5 8 11 14 17.
<h3>What is arithmetic progression?</h3>
The difference between every two successive terms in a sequence is the same; this is known as an arithmetic progression (AP). It is possible to obtain a formula for such nth term of a AP using this kind of development.
The numbers 5, 8, 11, 14,... belong to the arithmetic progression (AP) since they follow a pattern in which the previous number is added by 3 to get each new number.
nth term = a + (n-1)d
where, a is the initial term (=5)
n is the total terms in the series (=5)
d is the common difference (8-5=3)
Substitute the values in the formula to get the result;
5th term = 5 + (5-1)3
= 5 + (4×3)
5th term = 17
Therefore, the last term (5th term) of the series is 17.
