Abhasra spend half of her weekly allowance at the movies to earn more money her parents let her clean the windows in the house for seven dollars what is her weekly allowance if she ended with $12

her weekly allowance is $10

Step-by-step explanation:

Let x represent Abhasra's weekly allowance.

Abhasra spent half of her weekly allowance at the movies. This means that the total amount that she spent on the movies is x/2. The amount that she is left with would be

x - x/2 = x/2

In order to earn more money, her parents let her clean the windows in the house for seven dollars. This means that the total amount left with her is

x/2 + 7

if she ended with $12, it means that

x/2 + 7 = 12

x/2 = 12 - 7 = 5

x = 2 × 5 = $10

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
