Answer:

#1.---60%   #2.---$12.60 per hour

Step-by-step explanation:

#1. Since It was originally $50 you have 50% already, so what I did was I multiplied 50 by 2. this got me 100 which is a simpler way to calculate by. 50 to 80 dollars is a $30 change, so multiply that by 2 and you get 60. 60 will be your percent of change. You can double check this by multiplying 50 by .60, the answer will be 30 and 50+30=80

#2 Since Tyler starts off with $12 per hour with a 5% increase you will need to multiply 12*.05 this will get you the answer of 0.6 you then need to add $12, since that was his original payment. 12+0.6=12.60, so his final payment would by $12.60 per hour

devlian [24]
To compare the answers, you need to have the same denominator. 

We know that, 18 is a common denominator between 6 and 9. 

(5/6)*3/3 => 15/18 (ALMONDS) 
(7/9)*2/2 => 14/18 (CASHEWS) 

As seen, the weight of almonds is 1/18 bigger than the cashews.

Hope I helped :)
