Gerry will spend $13.6 in two weeks
From the problem given:
Gerry spend $1.25/day on lunch
Fridays spend extra $0.55
How much Gerry will spend in two weeks?
In one week, there are 5 school days
4 days (Monday to Thursday) Gerry spend $1.25/day
1 day, Fridays, Gerry spends $1.25+$0.55 = $1.80
So, in one week Gerry will spend :
= [tex]\boxed {(1.25 \times4) + 1.80\ }\\ =\boxed {5+1.80\ }\\ =\boxed {6.8\ }[/tex]
In two weeks, Gerry will spend :
[tex]=\boxed {2 \times 6.8\ }\\ =\boxed {13.6\ }[/tex]
