D. Peter’s Age + Two Times One Twin’s Age = Total Candles Needed

The answer is D because you are adding how many candles for whatever peters age is and since the twins are both the same age and get their own cake and the same amount of candles you multiply it by two

Answer:

D. Peter’s Age + Two Times One Twin’s Age = Total Candles Needed

Jenny has saved $3,800 over the last 12 months. She saved either $250 or $350 a month. During the 12 month period, how many times did Jenny save $250 for the month?

Answers

Answer:

Jenny save 4 times \$ 250 for the month

Step-by-step explanation:

Given Jenny has saved \$3,800 over the last 12 months.

She saved either \$250 or \$350 a month.

Let the number of months to save \$250 be x

Let the number of months to save \$350 be y

Total period is 12 month.

x+y=12 \ \ \ \ equation\ 1

Jenny has saved $3,800 over the last 12 months.

250x+350y=3800

Dividing both side from 50 we get,

(250)/(50)x+(350)/(50)y= (3800)/(50)

5x+7y=76 \ \ \ \ equation\ 2

Now Multiplying  equation 1 by 5 we get,

5*(x+y)=5* 12\n5x+5y=60\ \ \ \ equation \ 3

Now Subtracting Equation 3 by equation 2 we get,

(5x+7y=76)-(5x+5y=60)\n2y=16\ny=(16)/(2)= 8

Substituting the value of y in equation 1 we get,

x+y=12\nx+8=12\nx=12-8\nx=4

Jenny save 4 Months of  \$ 250 and 8 Months of  \$ 350in a 12 month duration

Answer:

4 times

Step-by-step explanation:

Let,

250 = x

350 = y

x + y = 12

250x + 350y = 3,800

Solve the system.

x = 4 and y = 8

Therefore, Jenny saved $250 for 4 months and $350 for 8 months.
