At a fish market, a pound of salmon costs $12 and a pound of shrimp costs $18. Mrs. Donnelly wants to buy 2 1/3 pounds of salmon
Semmy [17]

Answer:

Yes and she would have $2 left over because all the food costs $91.

Step-by-step explanation:

We should set up an equation so that everything makes sense. A calculator would be wise for this problem, but I am going to lay it out anyhow.

We should convert the mixed numbers to improper fractions to not be confused. 3 1/2 becomes 7/2 or 3.5 and 2 1/3 becomes 7/3.

From your wording, we can assume that the money Mrs. Donnelly has is either greater than or equal to $93.

Thus, we have 12*(7/3) + 18*(7/3) is equal to or greater than 93 (this is an inequality).

The math shows that the food costed 91 and so she only has $2 left.

seven less than the sum of p and t is as much as nine times a number y subtracted from 85 is seven times the sum of four and y
natita [175]

7-(p+t) =  9(85-n) = 7(4+y)

Algebra is a kind  of mathematics that includes symbols and the arithmetic operations across these symbols. These symbols do not have any fixed values and are called variables.  

An algebra expression contain coefficient variable and a constant

We apply various methods to solve those question

An algebra expression is also called an equation

let the number be x

Seven less than the of p and t

= 7-(p+t)…….(1)

Nine times a number y subtracted from 85

= 9(85-n)…..(2)

Seven times the sum of four and y

= 7(4+y)……(3)

Combining equations (1), (2) and (3) according to the question :

7-(p+t) =  9(85-n) = 7(4+y)
