5.75a + 6.5c = 53.25
a + c = 9
c = 9 - a
5.75a + 58.5 - 6.5a = 53.25
5.25 = 0.75a
a = 7
7 + c = 9
c = 2

Let us assume that cost of each granola bar be $x and that of a cup of yogurt be $y
From person A's purchase, we get
12x + 7y = 15.5; equation A
And from person B's purchase,
6x + 11y = 11.5; equation B
Let us multiply equation B by 2 and subtracting equation A from it, we will get
12x + 22y - 12x - 7y = 23 - 15.5,
=> 15y = 7.5
or, y = 0.5
Substituting value of y in equation A, we can find x
12x + 7*0.5 = 15.5
=> x = (15.5 - 3.5)/12
or, x = 1
Therefore, cost of granola bar is $1, and that of yogurt is $0.5
Answer:
<h2><u><em>
42</em></u></h2>
Step-by-step explanation:
56 : x = 16 : 12
x = 56 * 12 : 16
x = 672 : 16
x = 42
Answer:
1.
1/10 chance
2.
2/10 chance
3.
2/10 chance
4.
0/12 chance or maybe 0/10
Step-by-step explanation:
1.1/5 chance for the number and 1/2 chance for the heads/tails so
2.2/5 chance of getting it to land on an even number + 1/2 for heads
3..2/5 chance of getting it to land on an even number and 1/2 for tails
4.you cant land a 6
