Answer:
I found the table by an online search (it is below)
Sally has $7 to spend in candy.
The price of a chocolate bar is $1.50
The price of a lollipop is $0.75
The price of gumballs is $0.25
In the table, we have the following combinations.
a) 3 chocolate bars, 3 lollipops and 4 gumballs, the price is:
3*$1.50 + 3*$0.75 + 4*$0.25 = $7.75 (she can not buy this)
b) 3 chocolate bars and 4 gumballs, the price is:
3*$1.50 + 4*$0.25 = $5.50 (she can buy this)
c) 1 chocolate bar, 5 lollipops and 2 gumballs, the price is:
1*$1.50 + 5*$0.75 + 2*$0.25 = $5.75 (she can buy this)
d) 2 chocolate bars, 2 lollipops and 8 gumballs, the price is:
2*$1.50 + 2*$0.75 + 8*$0.25 = $6.50 (she can buy this)
Answer:
225
Step-by-step explanation:
The sum of this series is given by the formula:
Where
S_n is the sum
a is the first term (we get this by plugging in n = 1 into "2n-1", we have 2(1) - 1 = 1)
n is the number of terms (the sum is defined for n = 1 to n = 15, so 15 terms)
d is the common different (the difference is successive terms. Here, 2nd term would be 2(2) - 1 = 3, and first term was 1, so d = 3 -1 = 2)
<em>plugging in the info, we will get the sum:</em>
<em></em>
<em>The sum is 225</em>
