A road crew is putting sign on a 5 mile Road the first sign is the start of the road then they will place a sign every 500 yards
Grace [21]

Answer:

17

Step-by-step explanation:

There are 5,280 feet in a mile you want to multiply that by 5 for 5 miles

(5,280) (5) = 26,400

Since there are 3 feet in a yard you want to divide this number by 3

26,400/3 = 8,800

Then divide this by 500 for every 500 yards

8,800/500 = 17.6

Then round down because you can't have a decimal.

Therefore it is 17

A man earns 12,000 per year, 10% of it was spent on transport while 5% of the salary went as tax. He spent 80% of the remainder
weqwewe [10]

Answer:

Amount left = 2040

Step-by-step explanation:

Given that:

Per year salary = 12,000

Amount spent on transport = 10%

Transport = \frac{10}{100}*12000 = 0.1 * 12000

Transport = 1200

Tax = 5%

Tax = 0.05 * 12000

Tax = 600

Total = 1200 + 600 = 1800

Amount left = 12000 - 1800 = 10200

Food = 80% of remainder

Food = 0.8 * 10200

Food = 8160

Amount left after food = 10200 - 8160 = 2040

Hence,

Amount left = 2040
