Question

1. tricia has 40 cookies in her cookie jar. her 4 children each eat a cookie every day. 14a write an expression for the number of cookies left in the jar after m days. number of cookies = 40 - 4

Explanation:

Step1: Determine daily cookie consumption

Each of the 4 children eats 1 cookie daily, so total daily consumption is \(4\times1 = 4\) cookies.

Step2: Calculate total consumption after \(m\) days

After \(m\) days, the total number of cookies eaten is \(4\times m = 4m\) (since daily consumption is 4, over \(m\) days it's 4 times \(m\)).

Step3: Find remaining cookies

Initial cookies are 40. Subtract the total eaten (\(4m\)) from initial to get remaining: \(40 - 4m\).

Answer:

\(40 - 4m\)
