3 use table 3 to determine the cost for Option A when 0 minutes are used 4 calculate the tariff (cost per minute) for Option B using any point from the table 5 the two lines cross at a specific point on the graph. Use the graph to estimate the number of minutes where Option A becomes cheaper than Option B

Bongs, let's knock this out. 3.3 Step 1: Locate "TABLE 3: CELLPHONE COST DATA". Step 2: Find the row for "Option A Cost" and the column for "Minutes" equal to 0. From the table, when 0 minutes are used, the cost for Option A is R180. 3.4 Step 1: Choose a point from the "Option B Cost" row in Table 3. Let's use the point (50 minutes, R120). Step 2: Calculate the tariff (cost per minute) by dividing the total cost by the number of minutes. Tariff = Total CostMinutes Tariff = R12050 minutes Tariff = R2.40 per minute The tariff for Option B is R2.40 per minute. 3.5 Step 1: Locate the intersection point of the two lines on GRAPH 1. The two lines cross where their costs are equal. Step 2: Estimate the number of minutes (x-axis value) at this intersection point. The lines intersect approximately at 150 minutes. After this point, the line for Option A (lower line) is below the line for Option B (upper line). Option A becomes cheaper than Option B at approximately 150 minutes. Send me the next one 📸
