C) will not effected (the most frequent is still 600$)
Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
4 squared+ 12 squared= c squared
16+144=160
Square root 160
so your answer would be 12.6
