Mathematics

Answer:

Option B If Justin buys the hat and the jeans, solving the inequality 12x+65\leq 110 for x, will tell him the maximum number of bags of socks he can buy

Option D. If Justin buys the hat, jeans, and the maximum number of bags of socks, he will  have enough money left to buy a belt that is on sale for $7.99

Step-by-step explanation:

Let

x ----> the number of bags of socks

we know that

The number of bags of socks that Justin can buy multiplied by it cost, plus the cost of the hat plus the cost of a pair of jeans, must be at most $110

so

The inequality that represent this situation is

12x+25+40\leq 110

solve for x

Combine like terms left side

12x+65\leq 110

subtract 65 both sides

12x\leq 45

Divide by 12 both sides

x\leq 3.75

The maximum number of bags of socks is 3

If Justin buys the hat but not the jeans, then the inequality that represent this situation is

12x+25\leq 110

<u><em>Verify each statement</em></u>

case A) If x is the number of bags of socks Justin can buy, then the inequality  representing this situation is x < 3

The statement is false

The inequality that represent this situation is x\leq 3.75

The maximum number of bags of socks is 3

case B) If Justin buys the hat and the jeans, solving the inequality 12x+65\leq 110 for x, will tell him the maximum number of bags of socks he can buy

The statement is true

see the explanation

case C) If Justin buys the hat but not the jeans, solving the inequality 12x+40\leq 110  for x will tell him the maximum number of bags of socks he can buy

The statement is false

Because the inequality will be 12x+25\leq 110

case D) If Justin buys the hat, jeans, and the maximum number of bags of socks, he will  have enough money left to buy a belt that is on sale for $7.99

The statement is true

Because

The total cost is

12(3)+25+40=\$101

The amount of money left is \$110-\$101=\$9

\$9 > \$7.99

therefore

If Justin buys the hat, jeans, and the maximum number of bags of socks, he will  have enough money left to buy a belt

Part A

The equation is d = 50t

This is because the slope of 50 represents how many miles per day the butterflies cover (on average). The y intercept is 0 to indicate that 0 miles have been traveled initially.

You can think of this as the equation y = 50x

If t = 1, then d = 50t = 50*1 = 50 miles have been covered

If t = 2, then d = 50t = 50*2 = 100 miles have been covered

And so on.

==========================================================

Part B

You'll have these values in the bottom row (in the order presented): 50, 100, 150, 200, 250

You can plug in the values t = 1, t = 2, t = 3, t = 4 and t = 5 into d = 50t to find those answers in bold.

Or you could add on 50 each time to generate each new value. We start at 50 since t = 1 corresponds to d = 50.

==========================================================

Part C

You can keep the pattern of 50,100,150, ... going until you reach 2500. Then note the t value that pairs with d = 2500

In my opinion, that's the slower method.

The quicker method is to plug d = 2500 into the equation for part A, and then solve for t.

d = 50t

2500 = 50t

50t = 2500

50t/50 = 2500/50 ....... divide both sides by 50

t = 50

It will take 50 days for the average distance traveled to be 2500 miles.
