Answer:
$3.0375
Step-by-step explanation:
Original price of dinner = $2.25
If cost percentage of 35%, then the additional cost paid will be;
35% * 2.25

Target price = Original price + additional cost
Target price = $2.25 + $0.7875
Target price = $3.0375
It will be 42 because of the with times the 2nd highest
Given :-
- y varies directly as x, and y=14 when x=4.
To Find :-
- the value of y when x=9 .

- y = 7/2*9
- y = 63/2
- y = 31.5
6 is d, 7 is b, 8 is c, 9 is c
Answer: A 13.4
Step-by-step
a^2 + b^2= c^2 4^2 + b^2 = 14^2 16+ b^2= 195 b^2= 180 b= square root of 180 b= 6 square root of 5 or 13.42
