\$1.01

Step-by-step explanation:

Let the number of quarters Matthew has be x.

So, according to the question,

Number of dimes = 2x

Number of nickels = x

Number of penny = 1

Total number of coins = 9

Thus,

x + 2x + x + 1 = 9

4x = 8

So, x = 2

Now, we know that :

1 dime = \$0.10

1 quarter = \$0.25

1 nickel = \$0.05

1 penny = \$0.01

Thus, total money Matthew has = 2x(\$0.10) + x(\$0.25) + x(\$0.05) + 1(\$0.01)

Putting value of x,

Total money = 4(\$0.10) + 2(\$0.25) + 2(\$0.05) + 1(\$0.01)

= \$(0.40 + 0.50 + 0.10 + 0.01)

= \$1.01

Mathematics
Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
