Used paperback books are 0.25 and hardback books are 0.50 if you buy3 paperback book and 5 hardback books how much money do you spend

You need to multiply and add for this question.

0.25 x 3 = 0.75

0.50 x 5 = 2.50

Now add them together.

0.75 + 2.50 = 3.25

You spend $3.25.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
