Sarah wants to buy ingredients for her famous spaghetti sauce. She needs 2.5 pounds of ground beef, which costs $5.75 per pound, a jar of marinara sauce for $4.25, and a pack of spaghetti noodles for $2.10. If she also buys a loaf of garlic bread for $3.75, how much will she spend in total? Read more

Steps to Solve

1. Calculate the cost of ground beef

   Sarah needs 2.5 pounds of ground beef at a cost of $5.75 per pound.

   We can find the total cost of the beef as follows:

   $$ \text{Cost of ground beef} = 2.5 , \text{pounds} \times 5.75 , \text{dollars/pound} $$

2. Calculate the cost of marinara sauce

   Sarah buys one jar of marinara sauce for $4.25. The total cost is:

   $$ \text{Cost of marinara sauce} = 4.25 , \text{dollars} $$

3. Calculate the cost of spaghetti noodles

   Sarah purchases a pack of spaghetti noodles for $2.10. Therefore:

   $$ \text{Cost of spaghetti noodles} = 2.10 , \text{dollars} $$

4. Calculate the cost of garlic bread

   Sarah also buys a loaf of garlic bread for $3.75:

   $$ \text{Cost of garlic bread} = 3.75 , \text{dollars} $$

5. Sum all the costs

   Now, we need to add up all the costs:

   $$ \text{Total cost} = \text{Cost of ground beef} + \text{Cost of marinara sauce} + \text{Cost of spaghetti noodles} + \text{Cost of garlic bread} $$

   Plugging in the values:

   $$ \text{Total cost} = (2.5 \times 5.75) + 4.25 + 2.10 + 3.75 $$

6. Calculate the final total

   First, calculate the cost of ground beef:

   $$ 2.5 \times 5.75 = 14.375 $$

   Now sum all the costs:

   $$ \text{Total cost} = 14.375 + 4.25 + 2.10 + 3.75 $$

   $$ \text{Total cost} = 24.475 $$
