Kenna and Gracie each opened a checking account on the same day Kenna opened her account with$680and deposited $50per week from her babysitting earnings .Gracie opened her account with $950 and deposited $20 per week from her allowance model and solve an equation that can be used to find the num er of weeks it will take for their account balances to be equal

9 weeks

Step-by-step explanation:

Given

Kenna's Account

initial amount$680 and

deposited $50per week

The total amount for x number of weeks will be

y= 680+50x1

Gracie's Account

initial amount$950 and

deposited $20per week

The total amount for x number of weeks will be

y= 950+20x2

Step two:

equating the two equations above we have'

680+50x= 950+20x

solve for x

680-950=20x-50x

-270= -30x

divide both sides by -30

x= -270/-30

x=9 weeks

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
