(3•7) +5=26
write a situation for this equation and draw a picture that goes with it

For this case we have the following equation:

To do this, we propose the following situation:

Andrea raised $ 3 every day, for a week (including Saturday and Sunday), after helping her aunt decorating the garden.

In addition, Andrea had saved $5 from her father.

How much money does Andrea have in total?

So, if I raise $3 every day of the week we have:

To that amount we add $ 5:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
