Answer:
x = 48
Step-by-step explanation:
3x + 9 = 153
subtract 9 from both sides -9 -9
3x = 144
divide both sides by 3 3x/3 = 144/3
2x + (x + 9) = 153
2(48) + (48 + 9) = 153
96 + 57 = 153
153 = 153
Given:
cat carrier : 39.99
cat tower: 19.99
1st discount : 5%
2nd discount: 15% - cat tower
39.99 * 5% = 1.99
39.99 - 1.99 = 38
19.99 * (5% + 15%) = 19.99 * 20% = 3.99
19.99 - 3.99 = 16
38 + 16 = 54
