Answer:
222 = score in 2nd game
Step-by-step explanation:
Let x = score in 1st game
3/4(x) + 30 = score in 2nd game
x + 3/4(x) + 30 = 478 Multiply thru by 4 to eliminate the fraction
4x + 3x + 120 = 1912
7x + 120 = 1912
7x = 1792
x = 256
3/4(x) + 30 = 3/4(256) + 30
= 192 + 30
Check: 222 + 256 = 478
-3 | 9-8=1 | (-3, 1)
-2 | 4-8= -4 | (-2, -4)
-1 | 1-8=-7 | (-1, -7)
0. | 0-8=-8 | (0, -8)
1 | 1-8=-7 | (1, -7)
Caroline has $5.75 left
$25 - Caroline's money
$13 - field trip
$6.25 - lunch
$25 - ($13 + $6.25)
$25 - $19.25
= $5.75
