Answer:
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
First you find 10% by dividing by 10, to get 65, and then you can multiply 65 by 3 to get 195, which is 30%. If you have a calculator, you can just do 650 × 0.3 to get the same answer. Hope this helps!
