Step-by-step explanation:
Let calories present in apple = x
Then as per the question, calories present in banana= 2x-15
Total calories = 141
x+2x-15=141
3x= 141+15
3x= 156
x= 52
Calories present in apple = 52 calories
Calories present in banana = 2(52)-15
= 104-15= 89
Answer:
$10.50
Step-by-step explanation:
The equation would start off as 40x+4(1.5x)=483. Simplify from there, 40x+6x=483 -> 46x=483-> x=10.5
1.56 divided by 19.2 is 0.08125
I'm not sure this is 100% right, but it should be 8.16.
Hope this helps. :)
