**Step 1:**

Equation in T and t, T = 22 + 3t; t = 6 trips

**Step 2:**

T = 22 + 3t = 22 + 3(6) = 22 + 18 = 40 km

So, total distance walked, T = 40 km

**Step 1:**

Equation in T and w, T = 21 + 3w =36; w =?

**Step 2:**

T = 21 + 3w = 36; 3w = 36 − 21 = 15; w = $\frac{15}{3}$ = 5 weeks.

So, weeks to attend, w = 5

**Step 1:**

Equation in B and b, B = 8 + b; 1 bracelet = $3

Amount = $42

**Step 2:**

Number of new bracelets, b = $\frac{$42}{$3}$ = 14

B = 8 + b; B = 8 + 14 = 22.

So, Total number of bracelets, B = 22

**Step 1:**

Equation in J and d, J = 12 + 2d; d = 5

**Step 2:**

Number of liters of jam, J = 12 + 2d = 12 + 2(5) = 12 + 10 = 22 liters

So, Number of liters of jam, J = 22 liters.

**Step 1:**

Equation in S and d, S = 10 + 2d; S = 16

**Step 2:**

S = 10 + 2d = 16; 2d = 16 −10 = 6;

d = 6/2 = 3

So, Number of days of vacation, d = 3.

**Step 1:**

Equation in A and h, A = 80 + 5h; h = 5

**Step 2:**

A = 80 + 5h = 80 + 5(5) = 80 + 25 = $105;

So, total amount with Jim = A = $105

**Step 1:**

Equation in A and g, A = $125 + 8g; A = $221

**Step 2:**

A = 125 + 8g = 221; 8g = 221 − 125 = $96;

g = 96/8 = 12

So, no. of guests = g = 12

**Step 1:**

Equation in P and h, A = 32 + 5h; h = 6

**Step 2:**

P = 32 + 5h = 32 + 5(6) = 32 + 30 = 62;

So, no. of pages written = P = 62

**Step 1:**

Equation in S and w, S = 280 + 40w; w = 12

**Step 2:**

S = 280 + 40w = 280 + 40(12) = 280 + 480 = $760;

So, Total amount = S = $760

**Step 1:**

Equation in T and h, T = 90 + 12h; h = 6

**Step 2:**

T = 90 + 12h = 90 + 12(6) = 90 + 72 = $162;

So, Total bill amount = T = $162
