Question

Car Repairs: For these 3 exercises, use the graph below that shows the percent of all repairs for three car repair problems at a car repair shop.

Answer 1

oh the horizontal axis, the first one is brake system, for 21%
Then 14% is electrical.
Then 9% is transmission
on the vertical axis is all the percentages: percent of all repairs
The questions ask:
1) Suppose a mechanic repairs 478 cars. Predict how many repairs will be made on transmissions.
2)For every 100 repairs, predict how many more repairs will be made on a brake system problem than on an electrical problem.
3) Predict the percent of repairs that will be one of the 3 problems in the graph.
