Hey there!! 
The total cost is $52. 
She paid $12 more for the layer cake than the cupcake. 
Let's take the price of the cupcake as $x. Then, the price of the layer cake would be $12 + x 
The sum of these would result in $52. 
... x + x + 12 = 52 
... 2x + 12 = 52 
... 2x = 52 - 12 
... 2x = 40 
... x = 20 
Hence, the price of the cupcake is $20 and the price of the layer cake is $32. 
Hope my answer helps!!

Answer:
The answer to your question is:
a) sun to jupiter =  4.838 x 10 ⁸ miles
    sun to earth = 9.296 x 10 ⁷ miles
b) 5.2 times
Step-by-step explanation:
distance sun to jupiter = 483 800 000 miles
distance sun to earth = 92 960 000 miles
a) 
       sun to jupiter =  4.838 x 10 ⁸ miles  just move the decimal point eight places to the left.
       sun to earth = 9.296 x 10 ⁷ miles   just move the decimal point seven places to the left.
b) 
divide distance sun to jupiter by distance sun to earth = 
                                   = 4.838 x 10 ⁸ / 9.296 x 10 ⁷
                                  
First divide   4.838 by 9.296    or   4.838 / 9.296 = 0.52
Then we substract the powers:  8 minus 7  or 8 -7 = 1
So we get              0.52 x 10¹  or 0.52 x 10 = 5.2 times
