Final answer:
The cost of the sundae, c, can be represented by the equation c = 0.99 + (t - 1) * 0.25.
Step-by-step explanation:
The cost of the sundae, c, can be represented by the equation c = 0.99 + (t - 1) * 0.25.
- Let's analyze the given information:
- A sundae with 1 topping costs $0.99.
- A sundae with 4 toppings costs $1.74.
- A sundae with 7 toppings costs $2.49.
To find the equation representing the cost of the sundae, we can observe that for each additional topping, the cost increases by $0.25.Therefore, the base cost of the sundae is $0.99, and each additional topping adds $0.25 to the cost. So, for every topping beyond 1 (t - 1), an additional $0.25 is added to the base cost.Hence, the equation representing the cost of the sundae, c, given the number of toppings, t, is c = 0.99 + (t - 1) * 0.25.
