Sally wants to buy an assortment of candy. She has $7 dollars she can spend in the candy store. The candy store sells chocolate
1 answer:
Answer:
I found the table by an online search (it is below)
Sally has $7 to spend in candy.
The price of a chocolate bar is $1.50
The price of a lollipop is $0.75
The price of gumballs is $0.25
In the table, we have the following combinations.
a) 3 chocolate bars, 3 lollipops and 4 gumballs, the price is:
3*$1.50 + 3*$0.75 + 4*$0.25 = $7.75 (she can not buy this)
b) 3 chocolate bars and 4 gumballs, the price is:
3*$1.50 + 4*$0.25 = $5.50 (she can buy this)
c) 1 chocolate bar, 5 lollipops and 2 gumballs, the price is:
1*$1.50 + 5*$0.75 + 2*$0.25 = $5.75 (she can buy this)
d) 2 chocolate bars, 2 lollipops and 8 gumballs, the price is:
2*$1.50 + 2*$0.75 + 8*$0.25 = $6.50 (she can buy this)

Using an arithmetic sequence, it is found that the opera house will have 6150 chairs.
<h3>What is an arithmetic sequence?</h3>In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
In which is the first term.
The sum of the first n terms is given by:
In this problem, the sequence is:
Hence the first term and the common ratio are given, respectively, by:
Then the 50th term is:
The number of chairs is the <u>sum of the first 50 terms</u>, hence:
