You can set up a proportion. The quick answer is 600
7.5/900 = 2.5/x
x = 900 * 2.5 / 7.5
x = 900 * (1/3)
x = 300
But that is not the answer. The question is what does she save.
900 - 300 = 600
You could get the answer more directly. She does not eat 5 oz cake, so solve for that.
5/x = 7.5/900 Cross multiply
5 * 900 = 7.5 x
4500 = 7.5x Divide by 7.5
4500/7.5 = x
600 = x
Answer:
D) 4 x 10^5
Step-by-step explanation:
400,000
The number in scientific notation is between 1 and less than 10. We need to move the decimal 5 places to the left. Since we move 5 places to the left, our exponent is 10^5
4.0 * 10 ^5
Here in an idea:
lets say his total is repreented with the variable t.
lets say the number of bags of apples is represented by a.
t = a + 2
unless there is missing info.
