The total amount of money spent by Danny is [tex]\fbox{\$12.86}[/tex].
Further explanation:
Given:
Danny spends $5.87 on a photo, $2.49 for balloon and $4.50 on strawberries.
Calculation:
Consider the total money spent as [tex]S[/tex], money spends on photo as [tex]x[/tex], money spends on balloons as [tex]y[/tex] and money spend on strawberries as [tex]z[/tex].
Total money spent [tex]S[/tex] is written as the sum of the money spent on photo [tex]x[/tex], balloons [tex]y[/tex] and strawberries [tex]z[/tex] as follows:
[tex]S=x+y+z[/tex] …… (1)
Substitute, 5.87 for [tex]x[/tex], 2.49 for [tex]y[/tex] and 4.50 for [tex]z[/tex] in equation (1) to obtain the total money spent by Danny as follows:
[tex]\begin{aligned}S&=5.87+2.49+4.50\\&=8.36+4.50\\&=12.86\\\end{aligned}[/tex]
Thus, the total amount of money spent by Danny is [tex]\fbox{\$12.86}[/tex].
