3. If a shirt costs $30 and its price is reduced by 20%, what is the new price?
Solution:
To find the new price, we need to calculate the 20% reduction of $30 and subtract it from the original price.
20% of $30 = 0.20 * 30 = $6
New price = Original price - Reduction
New price = $30 - $6 = $24
Answer: b) $24
4. Solve the equation for x: 2x + 5 = 17
Solution:
To solve for x, we need to isolate x on one side of the equation.
Subtract 5 from both sides:
2x + 5 - 5 = 17 - 5
2x = 12
Next, divide both sides by 2 to find the value of x:
x = 12 / 2
x = 6
Answer: b) x = 6
