STEP 1

1. The cost to send one small package is $\$2.90$.
2. The cost to send one large package is $\$3.70$.
3. Hong is sending 1 small package and 4 large packages.
4. We need to calculate the total cost for sending these packages.

STEP 2

1. Calculate the cost for the small package.
2. Calculate the cost for the large packages.
3. Sum the costs to find the total cost.

STEP 3

Calculate the cost for sending 1 small package.
\text{Cost for 1 small package} = 1 \times 2.90 = \($\)2.90

STEP 4

Calculate the cost for sending 4 large packages.
$$\text{Cost for 4 large packages} = 4 \times 3.70$$

STEP 5

Perform the multiplication for the large packages.
$$4 \times 3.70 = 14.80$$

STEP 6

Add the costs of the small package and the large packages to find the total cost.
$$\text{Total cost} = 2.90 + 14.80$$

Perform the addition.
$$2.90 + 14.80 = 17.70$$ The total cost for sending 1 small package and 4 large packages is:
$$\boxed{17.70}$$
