Speed test cost $5 each and large one-topping pizzas cost $6 each write an equation that represents the total cost t of c large pizzas and d large one-topping pizzas

Equation t = 5c + 6d represents total cost t of c large pizzas and d large one-topping pizzas

Solution:

Given that

Cost of large pizza = $5 each

Cost of large one-topping pizza = $6 each

Need to write the equation that represents total cost t of c large pizzas and d large one topping pizzas.

From given information

Cost of 1 large pizza = 5

So cost of c large pizzas   = c x 5 = 5c

Cost of 1 large one-topping pizza = 6

So cost of d large one-topping pizzas   =d x 6 = 6d

Total cost t = cost of c large pizzas + cost of d large one-topping pizzas    

=> t = 5c + 6d

Hence equation t = 5c + 6d  represents total cost t of c large pizzas and d large one-topping pizzas.    

the answer is 99.
