Answer:
15+15+15+2+2+2+2=(3×15)+(4×2)=45+8=53
since the graph has direct variation as data in x axis increases y also increases.
so we need to find how many miles travelled per galloon .
we distance travelled per gallon =total distance travelled/galoons of fuel used.

for part b) slope=rise/run



slope of the graph is 2
Answer:
B.
Mn = Mn-1 + 125 for n > 1 ; M1 = 3,875
Step-by-step explanation:
Since they tell us after 1970, the first data would be that of 1971 and also that if we started since 1970, we do not know the data of 1969, therefore answer B is correct.
Replacing:
Let M1 = 1971 then Mn-1, that is M0 = 1970, we know that the population of 1970 the population is 3750, because it would be 125 less than the subsequent year, and in 1975 there are 3875. Therefore:
in n = 1
M1 = M0 + 125
3875 = 3750 + 125
this gives an equality, thus fulfilling the equation.
Answer:
35%
Step-by-step explanation:
35% percent of the cupcakes were mocha
The amount of decrease is $12.00 :$72.00 - $60.00 = $12.00
you then divide the amount of decrease by the original price to find the percent decrease:
$12.00 ÷ $72.00 = .166666... = 16.7%
