Lower limit: 800; upper limit: 1199

Step-by-step explanation:

The class limits of the third class is 800 for the lower limit and 1199 for the upper limit. This is because lower limit is the minimum limit while upper limit is the maximum limit. Therefore the lower limit is 800 and the upper limit is 1199.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
