Answer:
- 4
Step-by-step explanation:
Using the rule of exponents
• 
× 
⇔ 
• 
⇔ 
= 
= 
and right side
= 
× 
Hence
= 
× 
= 
Equating exponents on both sides gives
a + 10 = - 2a - 2 ( add 2a to both sides )
3a + 10 = - 2 (subtract 10 from both sides )
3a = - 12 ( divide both sides by 3 )
a = - 4
$18.40 with the tip added to the price because the tip will be $2.40
The answer is c because 1.5 times 1 = 1.5 then you add 2.5 to get 3.5
