Answer:
1 Dime
14 Quarters
Step-by-step explanation:
d + q = 15
0.10d + 0.25q = 3.60
d = 15 - q
0.10d + 0.25q = 3.60
0.10(15 - q) + 0.25q = 3.60
1.5 - 0.10q + 0.25q = 3.60
0.15q = 3.60 - 1.5
0.15q = 2.1
0.15q/0.15 = 2.1/0.15
q = 14
d = 15 - q
d = 15 - 14
d = 1
<span>The height of Gateway Arch shown on the Missouri quarter is 630 feet or 7,560 inches. Find how many 4 inch stacks of quarters make up the height of the Gateway Arch. If there are 58 quarter in 4 inch stack o, how many quarters high is the arch? </span>
<span>Hence to find how many 4 inch stacks of quarters make up the height of the </span><span>Gateway Arch,
Since the Gateway Arch is 7560 then for every stack is 4 inches to find the stacks all in all, we just have to divide 7560 / 4 = 1890
Then, to find </span><span>how many quarters high is the arch,
58 quarter x 4 inch = 232 quarters high in inches.
