Question

Every week, Farhan saves $x on Monday and he saves $1 more each day than
the previous day.
(a) How much money does Farhan save on Tuesday?
(b) How much does Farhan save altogether on Monday and Tuesday?
(c) Farhan saves $3 on Monday. How much does he save altogether on
Monday and Tuesday?​

Answer 1

The answer to the question could be:-

If Farhan saves $x (implies that, some amount of money) on Monday and he saves $1 more each day than the previous day every week, then-

(a) Amount Farhan saves on the previous day = $x

Amount Farhan saves more than the previous day = $1

Amount Farhan saves on Tuesday = x + 1

(b) Amount Farhan saves on Monday = $1x

Amount Farhan saves on Tuesday = $1x + 1

Amount Farhan saves altogether = 1x + (1x + 1) = 2x + 1

(c) Amount Farhan saves on Monday = $3

Amount Farhan saves on Tuesday = $3 + 1 = $4

Amount Farhan saves altogether = 3 + (3 + 1) = 6 + 1 = 7

Therefore Farhan saves $7 altogether {referring to (c)}.
