The science museum sells dinosaurs models to the town school and town library for $ 105 each. The town library buys 4 models. The school buys 6 models. What is the total cost of the models the town buys

Answer: Total cost of the models the town buy = $1050

Solution:

The science museum sells dinosaurs models to the town school and town library for $105 each.

The two library buys 4 models and cost of each model $105

Total cost pay by library = 4x105 = $420

The school buys 6 models and cost of each model $105

Total cost pay by school = 6x105 = 630

We need to calculate total cost of the models the town buys

Total cost = Cost buy library + Cost buy school

Total cost = 420+630

Total cost = $1050
