For 1. To estimate how many sports cards Alberto had, you would round each number to the nearest ten, so 318 would become 320. 273 would then become 270. You would then add those two and would get 590. So, Alberto had 590 sports cards (estimated). If you were looking for the actual answer (not estimated) , you would get 591.

Answer:
0.5025%
Step-by-step explanation:
The question is on increase and decrease
The old interest rate= .5%⇒0.5%
percentage increase= 1/2%= 0.5%
New rate= it requires you to increase 0.5 by 0.5%
New rate is ⇒100%+ 0.5%=100.5%
New rate⇒(100.5/100)×0.5 =0.5025
New rate as a decimal is 0.5025%
