If she needs to use 225g of flour for each cake and wants to make 18 cakes she will need 4050g (225x18=4050) of flour but she only has 360g which is obviously not enough flour. For one cake she needs 75g of sugar and since she needs to make 18 cakes she needs 1350g (75x18=1350) of sugar. She only has 135g so it’s not enough.
        
             
        
        
        
Answer:
72.7 is the weighted average score
Step-by-step explanation:
The weighted average score 
= score of lab * % share of total grade + score of first major test  * % share of total grade + score of second major test  * % share of total grade + Score of the final exam  * % share of total grade
Substituting the given values, we get - 
0.23 * 74 + 0.25 * 69 + 0.25 * 62 + 0.27 * 85 
= 72.7

Answer:
Final cost of the item is $19.55
Step-by-step explanation:
Expression representing the final cost of an item with original price = $p and discount = 15% will be,
Final cost = (p - 0.15p)
If the original price p = $23
By substituting p = 23 in the expression given,
Final cost after discount = 23 - (0.15)23
                                          = 23 - 3.45
                                          = $19.55
Therefore, final cost of the item is $19.55
