Let's denote the total cost of the drinks as $$ D $$ and the total cost of the sandwiches as $$ S $$.

Given:
- The cost of each drink is $$ \$1.75 $$.
- The cost of each sandwich is $$ \$7.50 $$.
- Jamal buys 4 drinks and 4 sandwiches.

We can write the equations to represent the total cost of the drinks and sandwiches as follows:

1. Total cost of drinks: $$ D = 4 \times \$1.75 $$
2. Total cost of sandwiches: $$ S = 4 \times \$7.50 $$

Now, we need to find the total cost of the lunch, which includes the cost of drinks, sandwiches, and the tip. Let's denote the total cost as $$ T $$.

The total cost of the lunch is the sum of the cost of drinks, sandwiches, and the tip:
$$ T = D + S + \$7 $$

Substitute the values of $$ D $$ and $$ S $$ into the equation:
$$ T = (4 \times \$1.75) + (4 \times \$7.50) + \$7 $$

Now, we can calculate the total cost of the lunch.
Calculate the value by following steps:
- step0: Calculate:
  $$\left(4\times 1.75\right)+\left(4\times 7.5\right)+7$$
- step1: Multiply the numbers:
  $$7+\left(4\times 7.5\right)+7$$
- step2: Multiply the numbers:
  $$7+30+7$$
- step3: Add the numbers:
  $$44$$
Let's calculate the total cost of Jamal's lunch. First, find the total cost of the drinks: 4 drinks × \$1.75 per drink = \$7.00 Next, find the total cost of the sandwiches: 4 sandwiches × \$7.50 per sandwich = \$30.00 Now, add the tip: \$7.00 (drinks) + \$30.00 (sandwiches) + \$7.00 (tip) = \$44.00 So, Jamal spends a total of \$44.00.
