Penny played two games of pac-man. the points she scored in her second game was 3/4 of the points she scored in her first game. she scored a total of 280 points from the two games. how many points did she score in her first game?

Since Penny scored a total of 280 points from the two games, she scored 40 points in her first game.

Given the following data:

To calculate how many points she scored in her first game:

Translating the word problem into an algebraic expression, we have;

  ...equation 1

  ....equation 2

Substituting eqn 1 into eqn 2, we have:

F = 40 points

160 points

Step-by-step explanation:

Let p = number of points scores in the first game.

3/4 p = number of points in the second game.

p + 3/4p = 280

4/4p + 3/4p = 280

7/4p = 280

p = 280 ÷ 7/4

p = 280 · 4/7

p = 160

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
