Answer:
Ms Patel bought 4 pliers, 2 wrenches and 1 plier set.
Explanation:
- First, make a ratio. For every 2 wrenches, she bought 4 pliers and 1 chisel set. This ratio would be written as (in pliers:wrenches:chisels)
4:2:1
- Then, multiply each of these numbers by their price, and add them together.
PLIERS: 4 × 17.50 = $70
WRENCHES: 2 × 21.50 = $43
CHISEL SETS: 1 x 28 = $28
TOTAL = $70 + $43 + $28 = $141
- As this adds up to $141, this shows that she bought 4 pliers, 2 wrenches and 1 chisel set.
