5. Marina volunteers at the Salvation Army. She has been tasked with buying non-perishable items for families that were displaced by a recent flood.
She finds a company willing to sell her cans of food at a discounted price.
In the system below x represents the number of small cans she purchased
and y represents the number of large cans she purchased.
2.25x + 4.75y = 714.75
x + y = 181
Part A: How many cans did Marina purchase?
Part B: What was the total amount Marina spent on the purchase?
Part C: How many small cans did Marina purchase?
Part D: How many large cans did Marina purchase?
Part E: How much does a small can cost?

step-by-step explanation:

answer: 12/52

step-by-step explanation: my reasoning is that there are 12 face cards in a deck and a total of 52 cards in all.

answer: i think it is c

the given growth  function for the length of the fish (cm) is

f(m) = 5(1.07)m = 5.35m

where 

m = months

at the end of the study, the length is 9.19 cm. the  time for conducting the study is determined as

5.35m = 9.19

m = 1.7178 months

part a.

the study was performed over a time period  of about 1.72 months. therefore  the domain for  plotting the function is 0 < = m < = 1.72.

note:

if growth  continues at this rate for up to m months, then the domain would be 0< =m< =m.

part b.

the growth function is a linear function.

when m=0, f=0.

therefore the initial growth is zero, which represents the y-intercept.

part c.

assume that the growth function is valid for 0< =m< =9.

the average rate of change of the function is the slope of the linear function, which is 5.35 cm/month.
