Question

An electric supply company raises its charge by 20% and s year later increases the new charges by 20%. If the total increase has been made all at once, to what percentage would it have been equialent.

Answer 1

Answer:

Step-by-step explanation:

the charges were $100 first year increases by 20%

so 100(1.2) = 120

second year increases again by 20%

120(1.2) = 144

the charges increase by $44 total.

$44 is 44% of 100.

it will be 44% for any amount of charges

so if the increases had been made all at once, it would be equivalent to 44%.
