Acommunity action committee is planning a block party. the party will be successful only if at least 70 adults and children attend. their budget for the party is $1,000, the cost for each adult will be $15, and the cost for each child will be $4. which system of inequalities models this situation?

a. a + c ≥ 70; 15a + 4c ≤ 1000
b. a + c ≤ 70; 15a + 4c < 1000
c. a + c ≥ 1000; 15a + 4c ≤ 70
d. a + c ≤ 70; 15a + 4c ≥ 1000

A. a + c ≥ 70; 15a + 4c ≤ 1000

Step-by-step explanation:

Given data:

A community action committee is planning a block party

The party will be successful if at least 70 adults (a) and children (c) attend

Their budget for the party is $1,000

The cost for each adult will be $15

And the cost for each child will be $4

Solution:

At least 70 adults and children attend.

So the inequality here is a + c ≥ 70

The budget for the party is $1,000.

So the cost for all adults plus the cost for all children cannot exceed $1,000

And hence the inequality here is; 15a + 4c ≤ 1,000

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
