Answer: $10

Step-by-step explanation:

Given

Robin and his four friends bought tickets for $\$12$ each

If each one of them bought a calculator then the total spendings are $\$110$

Suppose the cost of each calculator is $\$\ x$

Cost per person is given by $x+\$12$

For the group, it is $5(x+12)$

Equate this to total spendings

$\Rightarrow 5(x+12)=110\\\Rightarrow x+12=22\\\Rightarrow x=\$\ 10$

thus, the cost of each calculator is $\$ 10$

Answer:

( f + g ) (x) = $2 x^{2} + x - 4$

g(x) - f(x) = $x^{2} - 2 x - 4$

Step-by-step explanation:

f(x) = 4 x - 4 and g(x) = $2 x^{2} - 3 x$

( f + g ) (x) = f(x) + g(x)

= $4 x - 4 + 2 x^{2} - 2 x$

= $2 x^{2} + x -4$

2. g(x) = $x^{2} + 1$ and f(x) = 2 x + 5

g(x) - f(x) = $x^{2} + 1 - (2 x + 5)$

= $x^{2} + 1 - 2 x - 5$

= $x^{2} - 2 x - 4$
