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

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

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
