Last week, you finished level 2 of a video game in 32 minutes. today, you finish level 2 in 28 minutes. is the percent of change an increase or a decrease? what is your percent of change?

12.5%

There is a percentage decrease

Step by step explanation:  

Time took to finish level 2 last week = 32 minutes

Time took to finish level 2 today = 28 minutes  

The change in percentage =?

Step 1: Find the number of minutes that were decreased

32- 28 = 4 minutes

This means that it took 4 minutes less to finish the game today as compared to last week

Step 2: to find the percentage change  

(The difference of time took to complete the game / time took last week) * 100

(4 / 32) * 100

The change is 12.5%

80%

step-by-step explanation:

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.
