A test worth 125 points has 49 questions on it. Multiple Choice questions are worth 2 points each and short answer questions are
Charra [1.4K]

Answer:

There were 40 2-point questions and 9 3-point questions.

Step-by-step explanation:

To solve this situation, write two equations. One for the number of questions and one for the number of points.

Let x be the number of 2 point questions.

Let y be the number of 5 point questions.

x + y = 49

Now since x are each worth 2 points, the total points is 2x.

And since y are each worth 5 points, the total points is 5y.

So 2x + 5y = 125. Substitute one of the equations into the other to solve for the variables.

x + y = 49 becomes x = 49 - y. Substitute it.

2(49-y) + 5y = 125

98 - 2y + 5y = 125

98 + 3y = 125

3y = 27

y = 9

Substitute y = 9 back into the equation x = 49 - y to find x.

x = 49 - 9

x = 40

Last year, William made $620 babysitting. This year, he made 340% more money than he did last year. How much money did William m
STatiana [176]

Well it is a simple percentage question that we have to solve.

As we know that William made 620 by baby sitting and we also know that he made 340 per cent more next year so we can simply calculate 340 per cent of 620 and then add that percentage value to 620 to calculate the final answer.

So 340 / 100 * 620 equals to 2108 so the final answer is 2108 + 620 which becomes 2728.
