a)  2000 × 10% = 200

b)

2000 + 100u = 2200 + 75u

100u – 75u = 2200 – 2000

25u = 200

1u = 200 ÷ 25 = 8

100u = 100 × 8 = 800

800 + 2000 = \$2800

(a)
10% x 2000 = 200

(b)
In May —
spent : 100u ——- \$2000
saved : 100p
In June —
spent : 110u
saved : 75p

100u + 100p ——- 110u + 75p
25p ——- 10u
5p ——- 2u
100p ——- 40u
(2000/100) x 40 = 800
800 + 2000 = 2800

Ans : (a) \$200 more; (b) \$2800.

Spent            :      Saved

May             \$2000            :          4u

June            110%×\$2000 :         3u

=\$2200

2000 + 4u = 2200 + 3u

4u – 3u = 2200 – 2000

1u = 200

a) ? More spent in June

= \$2200 – \$2000

= \$200 (ans)

b) ? Earned each mth = \$2000 + 4u

= \$2000 + 4 ×\$200

= \$2800 (ans)

Spent : Saved
May \$2000 : 4u
June 110%×\$2000 : 3u
=\$2200
2000 + 4u = 2200 + 3u
4u – 3u = 2200 – 2000
1u = 200
a) ? More was spent un June
= 110% × \$2000
= \$2200 (Ans)
b) ? Earned each mth = \$2000 + 4u
= \$2000 + 4 ×\$200
