Answers

The answer is simple which is 55

Let B be the amount Beatrice charges per hour per child

Let x be the number of hours

Let n be the number of children

a)total amount Beatrice charges = T = B*x*n - 10

b)n =4 and T = 100

100 = B*x*4 -40

x = 35/B

c)Let S be the amount she has t o pay to her sister

n = 3 and x = (4+4+5) = 13

so, 13*B*3 -30 -S = 100

S = 39B - 130
