Question

At a bake shops the cost of flour is $2.50 per pound and increases at a rate of $0.07 per month.The cost of coca is $6.00 per pound and decreased at a rate of $0.03 per month. If the trends continue, which system of equations can be used to find the number of months, x, when the price is equal for both flour and coca

Answer 1

35 months

Explanation:

Let the number rod months be represented by x

At a bake shops the cost of flour is $2.50 per pound and increases at a rate of $0.07 per month.

For flour , the Equation

$2.50 + 0.07x

The cost of coca is $6.00 per pound and decreased at a rate of $0.03 per month.

For coca, the equation

$6.00 - $0.03x

If the trends continue, which system of equations can be used to find the number of months, x, when the price is equal for both flour and coca

We solve by equating both Equations together

Flour = Coca

$2.50 + 0.07x = $6.00 - $0.03x

0.07x + 0.03x = $6.00 - $2.50

0.1x = 3.50

x = 3.50/0.1

x = 35 months

Hence, the price is equal for both flour and coca after 35 months
