Eric has $115 to spend on back to school clothes. So far, he has spent $90. He also wants to buy socks, which cost $5 for each pair. a. Write an inequality to represent the greatest number of pairs of socks he can buy.

Given:

Total amount = $115

Amount spent = $90

Cost of each pair of socks = $5

To find:

The inequality to represent the greatest number of pairs of socks he can buy.

Solution:

Let x be the number of pairs of socks he can buy.

Cost of 1 pair of socks = $5

Cost of x pair of socks = $5x

Sum of amount spent and cost of x pair of socks must be less than or equal to the total amount he has.

Divide both sides by 5.

The maximum value of x is 5. So, the maximum number of pair of socks is 5.

Therefore, the inequality of the given situation is and represent the greatest number of pairs of socks he can buy.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
