Answer:
dr. potter provides 54 vaccinations TOTAL (including both measles and polio).
p+m=54
since there are 4 doses of polio and of measles, you have to use a variable to distinguish how many doses were given for measles and polio out of 142 given doses.
4p+2m=142
p+m=54
4p+2m=142
^^system of equation
p+m=54
4p+2m=142
p=54-m
4p+2m=142
(substitute 54-m to the equation)
4(54-m)+2m=142
m=37
(collect like terms, then substitute the value of m into the first equation)
p=54-37
p=17
(m, p)=(37, 17)

Put a point on -3 on y-axis and graph a straight line that is parallel to x-axis then color under the line because -3 is greater :)))

have a nice day
V=(hπr^2)/3, π≈3.14, h=7, r=2
V≈29.3 cm^2
152.30(0.15) = 22.845
Round 22.845 to $22.85
So the answer is C. (:
Hope this was helpful!
