Question

Andrew sells treats from his ice cream cart. The items he sells along with their peices are shown on the table. Suppose Andrew sells the quantities of each item given by the variables in the table.Part A) What does the expression 1.75a + 2.25b + 2.75a + 2.25c + 1.75b represent in the context of this problem? Part B)An expression equivalent to the one above is 4.5a + 4b + 2.25c. What does the first expression show about the quantities in this problem that the second expression does not show,​

Answer 1

a- the expression shows how much it would cost depending on how much of each item he sold.

b- The first expression shows the quantities of each pruduct as opposed to combinging the products (little unsure as their is no chart to go along with it)

Explanation:

Answer 2

Table:

item price quantity

frosty mango pop $1.75 a

frozen fruit yogurt $2.25 b

sundae swirl cup $2.75 a

chocolate chip cone $2.25 c

fudge sandwich $1.75 b

Answer:

A) 1.75a + 2.25b + 2.75a + 2.25c + 1.75b represents the addition of all prices of all the items included in the table. Once we are given the quantities, you can calculate total sales.

B) 4.5a + 4b + 2.25 just adds up all the a's and b's in the first equation, it also represents the addition of the prices included in the table.

C) the first equation showed the a's and b's separated in different products, while the second expression adds them up. Probably the a's represent products that are sold together as a combo, the same for the b's.
