Dani decides to add the cost of each shirt and the cost of each bag together, and then multiply by seven to find the total cost. Write an algebraic expression for the total cost of the gifts using Dani’s method. Remember, use t and b as your variables. (3 points)

Total cost of 7 pair = 7(t + b)

Step-by-step explanation:

Given:

Cost of each shirt = t

Cost of each bag = b

Number of pair = 7

Find:

Total cost

Computation:

Total cost of each pair = t + b

Total cost of 7 pair = 7(t + b)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
