Answer:
C) y=11x-135
Step-by-step explanation:
y-y1=m(x-x1)
y-19=11(x-14)
y=11x-154+19
y=11x-135
Answer:
$6300
Step-by-step explanation:
Using the equation of y=mx+c where c is constant, m is gradient then the two situations can be written as
2100=60x+c Equation 1
4800=150x+c Equation 2
Subtracting the terms of equation 1 from 2
(150-60)x=$4800-$2100
90x=$2700
x=$30
Substituting the value x into equation 1
60($30)+c=$2100
c=$2100-$1800=$300
c=$300
For 200 guests
y=200($30)+$300
y=$6000+$300=$6300
Answer:
The students baked 19 pies.
Step-by-step explanation:
Least total pieces of pies sold = 224
Number of pies donated by school cafeteria = 9
Number of pieces of pies donated by school cafeteria = 9×8 = 72
Number of pieces of pies baked = 224 - 72 = 152
Number of pies baked = 152 ÷ 8 = 192
