Solving a decimal word problem using a linear equation of the for...

Sindrei [870]

Answer:

5 pounds of coffee

Step-by-step explanation:

Let the number of pounds of coffee bought be 'x'.

Given:

Value on gift card = $90

Value of coffee per pound = $8.09

Money left after buying coffee = $49.55

Now, using unitary method,

1 pound cost = $8.09

∴ 'x' pounds cost = $8.09x$

Now, Money left = Total money on gift card - Cost of coffee.

$49.55=90-8.09x\\\\8.09x=90-49.55\\\\8.09x=40.45\\\\x=\frac{40.45}{8.09}=5$

Therefore, Lashonda bought 5 pounds of coffee.
