r=common ratio
a1=first term

and we notice we multiply the previous term by 3 to get the next term

therefor
a1=49
r=3

Craig bought 8 folders and notebooks for school folders costs 50 cents and notebooks costs a $50 Craig spent a total of $6 how m

stellarik [79]

The number of folders and notebooks in the equation is given by 3 and 5 respectively.

<h3>How to find number of folders and notebooks?</h3>

let

x = number of folders
y = number of notebooks

The equation:

x + y = 8

0.50x + 1.0y = 6

From (1)

x = 8 - y

Substitute x = 8 - y into (2)

0.50(8 - y) + 1.0y = 6

4 - 0.50y + 1.0y = 6

4 + 0.40y = 6

4 - 6 = -0.40y

-2 = - 0.40y

y = -2 / 0.40

y = 5

Recall

x + y = 8

x + 5 = 8

x = 8 - 5

x = 3
