7 2/3 bags of tortilla chips will last 2 days
3 5/6+ 3 5/6=6 10/6=7 2/3
Answer:
13
Step-by-step explanation:
The perimeter is calculated by multiplying the sum of width and height with 2
2*(4x-2+7x+9) = 300 solve inside the parenthesis
2*(11x+7) = 300 multiply inside the parenthesis with 2
22x + 14 = 300 subtract 14 from both sides
22x = 286 divide both sides by 22
x = 13
The initial cost is $45. To determine the increase, you need to follow two steps.
First you have to find what 7% of the original $45 is. This will tell us how much the cost will increase by.
To find 7% of $45, you need to multiply .07 x 45 = 3.15
This tells us that 7% of $45 = $3.15
Next, you have to add the increase to the original cost. This will be the new monthly cost.
$45 + $3.15 = $48.15
