Let x represent months
40 + 50x = 190 + 40x
Subtract 45 from both sides
40 + 10x = 190
Subtract 40 from both sides
10x = 150
Divide 10 by both sides and x = 15 months
Plug back in the 15 months for x
40 + 50(15)= $790
A strategy which would produce a new confidence interval with an <u>increased</u> margin of error is to: A. use a 98% confidence level.
<h3>What is a confidence interval?</h3>
A confidence interval simply refers to a range of estimated values which defines the probability that a population parameter will lie within it.
<h3>How to calculate the margin of error?</h3>
Mathematically, a margin of error is calculated by using this formula:

From the above formula, we can deduce that the margin of error is directly proportional to the critical value and inversely proportional to the square root of sample size.
This ultimately implies that, increasing the confidence level from 95% to 98% would <u>increase</u> the critical value and by extension the margin of error and vice-versa.

Answer:
780 calories
Step-by-step explanation:
Robert ate a carton of yogurt = 260 calories
he ate a sandwich = 425 calories
And he also ate an orange = 95 calories
Altogether he consumed = 260 + 425 + 95
= 780 calories.
