Explanation:

Step1: Define cost for each item

Cost of chicken: $3.80c$, cost of beef: $3.50b$, cost of salami: $2.90s$

Step2: Sum the individual costs

Total cost expression: $3.80c + 3.50b + 2.90s$

Step3: Substitute given values

Substitute $c=1$, $b=1.8$, $s=3.2$:
$3.80(1) + 3.50(1.8) + 2.90(3.2)$

Step4: Calculate each term

$3.80 + 6.30 + 9.28$

Step5: Sum the calculated terms

$3.80 + 6.30 = 10.10$; $10.10 + 9.28 = 19.38$

Answer:

Expression: $3.80c + 3.50b + 2.90s$
Total cost for given quantities: $19.38$
