Mrs. rodrigues was selling two kinds of raffle tickets for $1.50 and $3.50. the number of $1.50 tickets sold was 5 more than three times the number of $3.50 tickets sold. she earned a total of $1,607.50. how many $1.50 tickets were sold?

The number of $1.50 tickets sold is 605

Represent the $1.50 tickets with x, and the $3.50 tickets with y

So, the equations are:

Substitute 3y + 5 for x in the second equation

Open brackets

Collect like terms

Evaluate the like terms

Divide both sides by 8

Recall that:

So, we have:

Hence, the number of $1.50 tickets sold is 605

x = tickets

1.50(3x+5) +3.50x = 1607.50

4.50x +7.50 +3.50x = 1607.50

8.00x + 7.50 = 1607.50

8.00x = 1600

x = 1600/8 = 200 ( number of 3.50 tickets sold)

200*3 = 600+5 = 605

 there was 605 tickets sold for $1.50

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
