To find: We are asked to find the number of toppings did the sundae have for the total cost 2.80.
Answer to Problem 4STP
There are 3 toppings the sundae have.
Explanation of Solution
Given information:An ice cream sundae costs $1.75. Plus each additional toppings costs $0.35. Total cost is $2.80.
Calculation:
Let’s assign the number of toppings the sundae have as ‘ x’ .
So, we can set up equation as 1.75 + 0. 35x =2.80
Let’s solve the equation for ‘ x’ .
Subtract both sides 1.75
0. 35x =1.05
Divide both sides by 0.35
X =3
