Question

Ice creams are on a sale! Each ice cream costs $\$2$ less than the original price. David buys 3 of them and it costs him $\$18.$ Find the original price of each ice cream.

• A. $\$4$
• B. $\$5$
• C. $\$15$
• D. $\$8$

Answer 1

The correct option is D $\$8$

Number of ice creams bought $=\$3$
Let the original price of each ice cream be $\$x$
The selling price of each ice cream $=\$(x-2)$
Total selling price of 3 ice creams $=\$(x-2)\times 3=\$3(x-2)$

Given, total selling price of 3 ice creams is $\$18.$
$\Rightarrow 3(x-2)=18$

Step 1: Divide both sides by 3 to eliminate 3 on the left side of the equation.
$\frac{3(x-2)}{3}=\frac{18}{3}x-2=6$

Step 2: Add 2 to both sides of the equation to eliminate the constant on the left side of the equation.
$x-2+2=6+2x=8$

Hence, the original price of each ice cream is $\$8.$
