Answer:
28 quarters and 5 dimes
7(Q)+5(D)
7(4)+5(10)
28Q 50D Q=quarters D=dimes
it would be more efficient to do the substitution method bc its faster and easier
#1 - 2/3
#2 - 1 1/3
#3 - 2/3
#4 - 1 1/2
<span>40 <= x =<100 inequality shows the right answer.
Explanation:-
Since she has to reach the $200 mark by selling cakes at the rate of $5 each.
So, the minimum number of cakes should be 200/5 which is equals to 40.
Hence minimum value of number of cakes (x) = 40
It is given that She has 100 cakes this implies that maximum value of x can be 100.
hence X can be any value between 40 to 100 both inclusive.</span>
