Write an algebraic expression for the verbal description. the total cost of producing x units for which the fixed costs are $2800 and the cost per unit is $45

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

maya’s expression will generate the wrong sum because she violated the commutative property.

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
