8x + 2 cookies is made by all four girls altogether

Solution:

Given that,

Christy baked x number of cookies

Christy = "x" cookies

Amanda baked four cookies less than Christy

Which means,

Amanda = x - 4

Danielle bakes triple the amount of cookies as Christy

"triple" means three times

Therefore,

Danielle = 3x

Bonnie bakes six more cookies than Danielle

Which means.

Bonnie = 6 + 3x

How many cookies did all four girls bake altogether

Cookies made by all four girls = Christy + Amanda + Danielle + Bonnie

Cookies made by all four girls = x + x - 4 + 3x + 6 + 3x

Cookies made by all four girls = 8x + 2

Thus, 8x + 2 cookies is made by all four girls altogether
