Question

Mr smith is at Starbucks . He buys a muffin for $3.50 and a number of coffees for $2.50 each. If he only has 20$ in his pocket what is the maximum number of coffees he could buy

Answer 1

Answer:

6

Step-by-step explanation:

Given :

Cost of muffins = $3.50

Cost of coffee = $2.50 per coffee

Total amount held = $20

Let maximum number of coffees = x

Cost of muffins + (cost of coffee * x) ≤ 20

3.50 + 2.50x ≤ 20

2.50x ≤ 20 - 3.50

2.50x ≤ 16.50

Divide both sides by 2.50

2.50x / 2.50 ≤ 16.50 / 2.50

x ≤ 6.6

Hence, the maximum number of coffee that could be purchased is 6
