A fruit stall was selling pear at 70 cents each and apples at 40 cents each. Sally bought some pears and Tom bought some apples. Sally spent $1.10 more than Tom but had 7 less fruits than him.
a) How many pears did Sally buy?
b) How much did Tom spend?
0.40 x 7 = $2.80
1.10 + 2.80 = $3.90
0.70 - 0.40 = $0.30
3.90 ÷ 0.30 = 13 pears
a) It was 13 pears.
13 + 7 = 20
20 x 0.40 = $8
b) It was $8.
---------------------------------------
Alternative solution
---------------------------
0.70 x 7 = $4.90
4.90 + 1.10 = $6
0.70 - 0.40 = 0.30
6 ÷ 0.30 = 20
20 - 7 = 13 pears
a) It was 13 pears.
20 x 0.40 = $8
b) It was $8.
