Answer:

One penny

One nickel

Five dimes

One quarter total

Step-by-step explanation:

81 - 25(coins we know) = 56 cents left

So we know we need 1 penny

Then 4 coins make up 55 cents, so that's a quarter & 3 dimes

Samantha needs to bake at least 120 pot pies to sell at her restaurant. she can bake 12 pot pies per hour and 15 veggie pot pies
Veronika [31]

Answer:

y>(line under >) - 4/5x + 8

Step-by-step explanation:

Phrase "at least" indicates that the total number of pies is greater than or equal to 120.

The number of chicken pot pies Samantha makes is 12x, and the number of veggie pot pies she makes is 15y.

Use this information to create the inequality:

12x + 15y >(line under >) 120

Simplify by solving for y to get this inequality:

y >(line under >) - 4/5x + 8
