Ms. chen is planning to take her camp group on a field trip to pottery bayou where each person will create her own piece of art pottery. the regular cost is $20 per person. there is a group special that costs $10 per person with an additional $50 fee for a private room. ms. chen is trying to decide if she should use the regular price or the group special. write an equation in slope intercept form to show the total cost of the regular price with x people (1 point) slope intercept form: y=mx+b if b=0, you can simply use y=mx regular cost: y= group special cost: y=

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
