Tallulah has a dimes and y nickels. She has at most 18 coins worth at
nexus9112 [7]

One possible solution for the system of inequalities is given as follows:

13 dimes and 2 nickels.

<h3>How to obtain the system of inequalities?</h3>

The first step in obtaining the system of inequalities is identifying the variables, which are given as follows:

  • Variable x: number of dimes that Tallulah has.
  • Variable y: number of nickels that Tallulah has.

Tallulah has at most 18 coins, hence:

x + y ≤ 18.

A nickel is worth 5 cents = $0.05, while a dime is worth 10 cents = $0.1, and Tallulah has at least $1.20 combined, hence:

0.1x + 0.05y ≥ 1.20.

The solution is given by the shaded region on the image given at the end of the answer, and one possible solution is given as follows:

x = 13, y = 2.

Which means that she has 13 dimes and 2 nickels.
