Answer:
986
if they mark that wrong, the smart alek answer where its correct universally is
Step-by-step explanation:
Significant Figures are a pain, however for this one, multiplying its the greatest number of digits.
1 - Solve the equation
70.4 x 14 = 985.6
Because 7 has 3 significant figures the final answer must also, and the most annoying thing about it, is that we have to convert 4 SF's to 3, which is where scientific notation is of use.
9.85 x
However because I doubt you were taught this, they probably just want 986 which is the rounded version
Hope this helps,
1. For the first question, asking to write an equation for how much more Max needs to save up, It would simply be 95.00 + n = 150.00.
This is because he has $95 and needs $n more to get to the final amount of $150.
2. For the second question, asking which number being substituted for n makes the equation true, isolate n in the equation to find what it equals. To do this, subtract 95 from both sides.
95 + n - 95 = n < This isolates the variable.
150 - 95 = 55
This means n = 55 (fifty five)
3. The inequality is a bit more complicated since it says less than $5 per week. The way I'd do it would get some kind of answer but because I haven't done inequalities like this in a while, I unfortunately can't help you with this part. I can say, however, that it more than likely has something to do with being between two values, but I'm not sure. Sorry for the inconvenience.
