Answer:
$927.113
Step-by-step explanation:
50-7=43
43×18.94=814.42
100-15=85
100%=18.94
what about 85%
85×18.94=1609.9÷100=16.099
16.099×7=112.693
814.42+112.693= 927.113
Answer:
With base of 3: 
With base of 9: 
Step-by-step explanation:
Use 3 and 9 as the base of the power.

Amber spends $5,307.25 and she can make 461 skateboards.
Divide 1846 by 2 and you get 923, you then multiply that by $5.75 and get $5,307.25.
Then, you'll divide 1,845 by 4 and get 461.5. (she can only make 461 full skateboards.)
-3(x+(3))^2-4 is the answer
