Answer: At least 32 calendars.
Step-by-step explanation:
Since they already have $350 out of the $600, they only need to raise $250 more (600-350).
Each calendar is $8
To find how many calendars are needed to raise $250, divide it by $8 (250/8=31.25)
Since you cannot sell .25 of a calendar it would round up to be 32.
Grou plike terms
4b+9a-2a+5b
4b+5b+9a-2a
9b+7b
the closest one is C, but that has -7b instead of +7b
It would take 16 hours for it to empty.
Answer:
equation is the best model of the data: y=0.5x+2.4
Step-by-step explanation:
y=2.8(1.1^x)
try two points (2,3.5) and(1,3)
find m=y2-y1/x2-x1
m=3-3.5/1-2=
m=0.5
find b at point 1,3
y=mx+b
3=0.5(1)+b
b=3-0.5
b=2.5
