Distribute 5 to terms: We are given the function c(n)=−6+5(n−1). The first step is to distribute the 5 to both terms inside the parentheses.Calculation: c(n)=−6+5×n−5×1
Combine like terms: Now, we simplify the expression by combining like terms.Calculation: c(n)=5n−6−5
Combine constants: Further simplifying the expression by combining the constants −6 and −5.Calculation: c(n)=5n−11
