Answer:

The cheapest is the Kenyan tea which costs £1.05 for each 100g.

Step-by-step explanation:

200 g of Kenyan tea costs £2.10

1. Calculate the rate of each gram, by dividing 2.10/200

0.0105 x 100 = £1.05 for each 100g

300 g of Columbian tea costs £3.45

1. Calculate the rate of each gram, by dividing 3.45/300

0.0115 x 100 = £1.15 for each 100g

1. Calculate the rate of each gram, by dividing 1.70/150

150 g of Indian tea costs £1.70

0.01133333333 x 100 = £1.133333333 for each 100g

B) The cheapest is the Kenyan tea which costs £1.05 for each 100g.

Variables:
p = uniform pants
c = baseball caps

Equations:
$2p + 2c = 68$
$p - c = 12$
****************************************************************************************
Step 1.
$\left {{2p+2c=68} \atop {p-c=12}} \right$

Step 2.
$\left {{2p+2c=68} \atop {2(p-c=12)}} \right.$

Step 3.
$\left {{2p+2c=68} \atop {2p-2c=24}} \right.$

Step 4.
$4p = 92$

Step 5.
$\frac{4p}{4} = \frac{92}{4}$
$p=23$

Step 6.
$p-c=12$
$23 - c=12$
<u /> $23=12+c$
<u /> $11=c$
<u />
Baseball Pants = $23
Baseball Caps = $11
