Answer 1

Answer:

X Company charges $(0.2+0.01n)\times 10^2 \ cents$ more than Company Y

Step-by-step explanation:

Given:

Cost of X company = $\ 0.35+(\ 0.05\times 1 \ minute)$

Cost of Y Company =$\ 0.15+(\ 0.04\times 1 \ minute)$

for n minutes

Cost of X company for n minutes = $\ 0.35+(\ 0.05\times n \ minute)$

Cost of Y Company for n minutes =$\ 0.15+(\ 0.04\times n \ minute)$

Difference for n minutes we get by Subtracting Cost of Y Company for n minutes by Cost of X company for n minutes

Difference for n minutes = $(\ 0.2+\ 0.01n)$=$(0.2+0.01n)\times 10^2 \ cents$

X Company charges $(0.2+0.01n)\times 10^2 \ cents$ more than Company Y
