An ice cream sundae costs $1.75 plus an additional $0.35 for each topping. if the total
cost is $2.80, how many toppings did the sundae have?

3

Step-by-step explanation:

$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80

1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75

2) Substract the numbers: 0.35x=1.05

3) Divide the both sides of the equation by 0.35

4) x=3
