Laura bought a biscuit packet for (4x square+3) and a tea powder for (5x-2) how much did she spend

To find out how much Laura spent, we need to add the cost of the biscuit packet and the cost of the tea powder.

The cost of the biscuit packet is \( 4x^2 + 3 \), and the cost of the tea powder is \( 5x - 2 \).

The total amount Laura spent is:

\[
(4x^2 + 3) + (5x - 2)
\]

Now, let's simplify this expression by combining like terms:

\[
4x^2 + 5x + 3 - 2
\]

Simplifying further:

\[
4x^2 + 5x + 1
\]

So, Laura spent a total of \( 4x^2 + 5x + 1 \).

Here are 5 related questions:
1. What if Laura bought two packets of biscuits? What would be the total cost?
2. How much would Laura spend if \( x = 2 \)?
3. What would be the cost difference if the price of the tea powder was \( 7x - 2 \)?
4. If the cost of the biscuit packet was reduced by 2, what would the new total cost be?
5. How would the total cost change if the price of the tea powder doubled?
