Ricarda earns a $25 allowance each week . how much allowance will she earn after 7 weeks? use an erea model to solve.

well what you can is easy and ill explain and show you easy and simple :)

K , so Ricarda earns a total of $25 per week . Now the questioner is asking how much will she get after 7 weeks is through?

so what you would do is grab the total sum of each week's allowance ($25) , then your going to grab the 7 for how many weeks went through ... now what you do is multiply cause its asking in the future of the amount she will have from the allowances .. so you would do ( 25 * 7) =175 .. so as you can see , she will get $175 from the 7 week of allowance and that was easy to simplify in a easy way where you would get the direct answer .. so u would do 25*7=$175 < answer

I don't know how to draw a model on here so I would recommend for someone else to draw it or get the information from the paragraph and make a model from that info

hope this helps and have a nice day!

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
